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

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. 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. Note: At the top of the third column, highlight L3. Then press 2nd and 1 to create L1, followed by a minus sign, then press 2nd and 2 to create L2.

Leave this set to 1. To test this, they conduct an experiment in which they measure the mpg of 11 cars with and without the fuel treatment. This means we do not have sufficient evidence to say that there is any difference between the average mpg of the two groups. If not, move the cursor next to List: and press [2nd] [1].
