How to do a paired t test on ti 84

The following example demonstrates how to perform a T-Test calculation. If not, move the cursor next to List: and press [2nd] [1]. This means the mu m is greater than the alternate hypothesis m 0.

A paired samples t-test is used to compare the means of two samples when each observation in one sample can be paired with an observation in the other sample. This tutorial explains how to conduct a paired t-test on a TI calculator. Researchers want to know if a new fuel treatment leads to a change in the average mpg of a certain car. To test this, they conduct an experiment in which they measure the mpg of 11 cars with and without the fuel treatment. Since each car receives the treatment, we can conduct a paired t-test in which each car is paired with itself to determine if there is a difference in average mpg with and without the fuel treatment. Perform the following steps to conduct a paired t-test on a TI calculator.

A two sample t-test is used to test whether or not the means of two populations are equal. This tutorial explains how to conduct a two sample t-test on a TI calculator. Researchers want to know if a new fuel treatment leads to a change in the average mpg of a certain car. To test this, they conduct an experiment in which 12 cars receive the new fuel treatment and 12 cars do not. For the control group, the mean mpg is 21 mpg and the standard deviation is 2. For the treatment group, the mean mpg is Use this data to perform a two sample t-test to determine if the average mpg is different between the two groups. Press Stat. Our calculator will automatically produce the results of the two sample t-test:. Because the p-value of the test 0.

A one sample t-test is used to test whether or not the mean of a population is equal to some value. This tutorial explains how to conduct a one sample t-test on a TI calculator. Researchers want to know if a certain type of car gets 20 miles per gallon or not. They obtain a random sample of 74 cars and find that the mean is Use this data to perform a one sample t-test to determine if the true mpg for this type of car is equal to 20 mpg.

This means we do not have sufficient evidence to say that there is any difference between the average mpg of the two groups. To perform the paired t-test, we will simply perform a t-test on column L3, which contains the values for the paired differences.

A paired samples t-test is used to compare the means of two samples when each observation in one sample can be paired with an observation in the other sample.

First, we will input the data values for both samples. This is the standard deviation of the differences. All rights reserved. The following example demonstrates how to perform a T-Test calculation.
