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].

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. First, we will input the data values for both samples.

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.

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. Then press 2nd and 1 to create L1, followed by a minus sign, then press 2nd and 2 to create L2. Enter the following values for the control group no fuel treatment in column L1 and the values for the treatment group variable received fuel treatment in column L2, followed by the difference between these two values in column L3.
