uEstimated Value Calculation for Regression Graphs

The STAT Mode also includes aY-CAL function that uses regression to calculate the

estimated y-value for a particular x-value after graphing a paired-variable statistical

regression.

The following is the general procedure for using the Y-CAL function.

1. After drawing a regression graph, press 6(g)2(Y-CAL) to enter the graph selection mode,

and then press w.

If there are multiple graphs on the display, use f and c to select the graph you want, and

then press w.

•

This causes an x-value input dialog box to appear.

2. Input the value you want for x and then press w.

•

This causes the coordinates for x and y to appear at the bottom of the display, and moves the

pointer to the corresponding point on the graph.

3. Pressing v or a number key at this time causes the x-value input dialog box to reappear

so you can perform another estimated value calculation if you want.

4. After you are finished, press i to clear the coordinate values and the pointer from the

display.

The pointer does not appear if the calculated coordinates are not within the display range.

The coordinates do not appear if [Off] is specified for the [Coord] item of the [SETUP] screen.

The Y-CAL function can also be used with a graph drawn by using DefG feature.

uRegression Formula Copy Function from a Regression Calculation Result

Screen

In addition to the normal regression formula copy function that lets you copy the regression

calculation result screen after drawing a statistical graph (such as Scatter Plot), the STAT Mode

also has a function that lets you copy the regression formula obtained as the result of a regression

calculation. To copy a resulting regression formula, press 6(COPY).

k Tests, Confidence Interval, and Distribution Calculations

The STAT Mode includes functions for performing tests, and confidence interval and distribution

calculations.You can find explanations of each of these functions in the following sections: 1-2

Tests, 1-3 Confidence Interval, and 1-4 Distribution.

uParameter Settings

The following describes the two methods you can use to make parameter settings for test,

confidence interval, and distribution calculations.

• Selection

With this method, you press the function key that corresponds to the setting you want to

select from the function menu.

• Value Input

With this method, you directly input the parameter value you want to input. In this case,

nothing appears in the function menu.

· Pressing i returns to the list input screen, with the cursor in the same position it was at

before you started the parameter setting procedure.

· Pressing ! i(QUIT) returns to the top of list input screen.

· Pressing w without pressing 1(CALC) under “Execute” item advances to calculation

execution.To return to the parameter setting screen, press i, A, or w.

uCommon Functions

• The symbol “ ” appears in the upper right corner of the screen while execution of a

■

calculation is being performed and while a graph is being drawn. Pressing A during this

time terminates the ongoing calculation or draw operation (AC Break).

• Pressing i or w while a calculation result or graph is on the display returns to the

parameter setting screen. Pressing ! i(QUIT) returns to the top of list input screen.

· Pressing A while a calculation result is on the display returns to the parameter setting screen.

• Pressing u 5(G↔T) after drawing a graph switches to the parameter setting screen

(G↔T function). Pressing u 5(G↔T) again returns to the graph screen.

· The G↔T function is disabled whenever you change a setting on the parameter setting screen, or

when you perform a u 3(SET UP) or ! K(V-Window) operation.

• You can perform the PICT menu's screen save or recall functions after drawing a graph.

· The ZOOM function and SKETCH function are disabled.

The TRACE function is disabled, except for the graph display of two-way ANOVA.

The graph screen cannot be scrolled.

• After drawing a graph, you can use a Save Result feature to save calculation results to a

specific list. Basically, all items are saved as they are displayed, except for the first line title.

· Each time you execute Save Result, any existing data in the list is replaced by the new results.

Tests (TEST)

1-2 Tests (TEST)

The Z Test provides a variety of different standardization-based tests. They make it possible

to test whether or not a sample accurately represents the population when the standard

deviation of a population (such as the entire population of a country) is known from previous

tests. Z testing is used for market research and public opinion research, that need to be

performed repeatedly.

1-Sample Z Test tests for the unknown population mean when the population standard

deviation is known.

2-Sample Z Test tests the equality of the means of two populations based on independent

samples when both population standard deviations are known.

1-Prop Z Test tests for an unknown proportion of successes.

2-Prop Z Test tests to compare the proportion of successes from two populations.

The t Test tests the hypothesis when the population standard deviation is unknown.The

hypothesis that is the opposite of the hypothesis being proven is called the null hypothesis,

while the hypothesis being proved is called the alternative hypothesis. The t-test is normally

applied to test the null hypothesis. Then a determination is made whether the null hypothesis

or alternative hypothesis will be adopted.

1-Sample t Test tests the hypothesis for a single unknown population mean when the

population standard deviation is unknown.

2-Sample t Test compares the population means when the population standard deviations

are unknown.

LinearReg t Test calculates the strength of the linear association of paired data.

χ Test tests hypothesis concerning the proportion of samples included in each of a number

of independent groups. Mainly, it generates cross-tabulation of two categorical variables

(such as yes, no) and evaluates the independence of these variables. It could be used, for

example, to evaluate the relationship between whether or not a driver has ever been involved

in a traffic accident and that person’s knowledge of traffic regulations.

2-Sample F Test tests the hypothesis for the ratio of sample variances. It could be used, for

example, to test the carcinogenic effects of multiple suspected factors such as tobacco use,

alcohol, vitamin deficiency, high coffee intake, inactivity, poor living habits, etc.

ANOVA tests the hypothesis that the population means of the samples are equal when there

are multiple samples. It could be used, for example, to test whether or not different

combinations of materials have an effect on the quality and life of a final product.

One-Way ANOVA is used when there is one independent variable and one dependent

variable.

Two-Way ANOVA is used when there are two independent variables and one dependent

variable.

Perform analysis of variance on the following null hypothesis, using a significance level of

5%.

Ho : No change in strength due to time

Ho : No change in strength due to heat treatment temperature

Ho : No change in strength due to interaction of time and heat treatment temperature

uSolution

Use two-way ANOVA to test the above hypothesis.

Input the above data as shown below.

List1={1,1,1,1,2,2,2,2}

List2={1,1,2,2,1,1,2,2}

List3={113,116,139,132,133,131,126,122}

Define List 3 (the data for each group) as Dependent. Define List 1 and List 2 (the factor

numbers for each data item in List 3) as Factor A and Factor B respectively.

Executing the test produces the following results.

• Time differential (A) level of significance P = 0.2458019517

The level of significance (p = 0.2458019517) is greater than the significance level (0.05),

so the hypothesis is not rejected.

• Temperature differential (B) level of significance P = 0.04222398836

The level of significance (p = 0.04222398836) is less than the significance level (0.05), so

the hypothesis is rejected.

• Interaction (A × B) level of significance P = 2.78169946e-3

The level of significance (p = 2.78169946e-3) is less than the significance level (0.05), so

the hypothesis is rejected.

The above test indicates that the time differential is not significant, the temperature

differential is significant, and interaction is highly significant.

Confidence Interval (INTR)

1-3 Confidence Interval (INTR)

A confidence interval is a range (interval) that includes a statistical value, usually the

population mean.

A confidence interval that is too broad makes it difficult to get an idea of where the population

value (true value) is located. A narrow confidence interval, on the other hand, limits the

population value and makes it difficult to obtain reliable results. The most commonly used

confidence levels are 95% and 99%. Raising the confidence level broadens the confidence

interval, while lowering the confidence level narrows the confidence level, but it also

increases the chance of accidently overlooking the population value. With a 95% confidence

interval, for example, the population value is not included within the resulting intervals 5% of

the time.

When you plan to conduct a survey and then t test and Z test the data, you must also

consider the sample size, confidence interval width, and confidence level. The confidence

level changes in accordance with the application.

1-Sample Z Interval calculates the confidence interval for an unknown population mean

when the population standard deviation is known.

2-Sample Z Interval calculates the confidence interval for the difference between two

population means when the population standard deviations of two samples are known.

1-Prop Z Interval calculates the confidence interval for an unknown proportion of

successes.

2-Prop Z Interval calculates the confidence interval for the difference between the propotion

of successes in two populations.

1-Sample t Interval calculates the confidence interval for an unknown population mean

when the population standard deviation is unknown.

2-Sample t Interval calculates the confidence interval for the difference between two

population means when both population standard deviations are unknown.

On the initial STAT Mode screen, press 4 (INTR) to display the confidence interval menu,

which contains the following items.

• 4(INTR)b(Z) ... Z intervals (p. 1-3-3)

uGeneral Confidence Interval Precautions

Inputting a value in the range of 0 < C-Level < 1 for the C-Level setting sets you value you

input. Inputting a value in the range of 1 < C-Level < 100 sets a value equivalent to your input

divided by 100.

# Inputting a value of 100 or greater, or a

negative value causes an error (Ma ERROR).

Distribution (DIST)

1-4 Distribution (DIST)

There is a variety of different types of distribution, but the most well-known is “normal

distribution,” which is essential for performing statistical calculations. Normal distribution is a

symmetrical distribution centered on the greatest occurrences of mean data (highest

frequency), with the frequency decreasing as you move away from the center. Poisson

distribution, geometric distribution, and various other distribution shapes are also used,

depending on the data type.

Certain trends can be determined once the distribution shape is determined.You can

calculate the probability of data taken from a distribution being less than a specific value.

For example, distribution can be used to calculate the yield rate when manufacturing some

product. Once a value is established as the criteria, you can calculate normal probability

when estimating what percent of the products meet the criteria. Conversely, a success rate

target (80% for example) is set up as the hypothesis, and normal distribution is used to

estimate the proportion of the products will reach this value.

Normal probability density calculates the probability density of normal distribution from a

specified x value.

Normal distribution probability calculates the probability of normal distribution data falling

between two specific values.

Inverse cumulative normal distribution calculates a value that represents the location

within a normal distribution for a specific cumulative probability.

Student- t probability density calculates t probability density from a specified x value.

Student- t distribution probability calculates the probability of t distribution data falling

between two specific values.

Like t distribution, distribution probability can also be calculated for χ , F, Binomial, Poisson,

and Geometric distributions.

On the initial STAT Mode screen, press 5 (DIST) to display the distribution menu, which

contains the following items.

• 5(DIST)b(Norm) ... Normal distribution (p. 1-4-3)

c(T) ... Student-t distribution (p. 1-4-7)

d(χ ) ... χ distribution (p. 1-4-9)

e(F) ... F distribution (p. 1-4-12)

f(Binmal) ... Binomial distribution (p. 1-4-16)

g(Poissn) ... Poisson distribution (p. 1-4-19)

h(Geo) ... Geometric distribution (p. 1-4-21)

uCommon Distribution Functions

After drawing a graph, you can use the P-CAL function to calculate an estimated p-value for

a particular x value.

The following is the general procedure for using the P-CAL function.

1. After drawing a graph, press 1 (P-CAL) to display the x value input dialog box.

2. Input the value you want for x and then press w.

• This causes the x and p values to appear at the bottom of the display, and moves the

pointer to the corresponding point on the graph.

3. Pressing v or a number key at this time causes the x value input dialog box to reappear

so you can perform another estimated value calculation if you want.

4. After you are finished, press i to clear the coordinate values and the pointer from the

display.

and P, respectively.
