JMP Session Lab 1 (assn 2) Objectives: Open a data set. Assign the appropriate data types (continuous, ordinal, categorical) to a column of data ... one showing the distribution of TFAT0 for people in group 1 and one showing TFAT0 for people in group 2. Notice that this gives you the sample size, mean and SD of the data (ie, descriptive ...

Hypothesis Test: 1) 2) Choose Test statistic. 3) Compute test statistic. 4) Find p-value (use . t-Probability Calculator.JMP) 5) Make decision and interpret. To perform a t-test in JMP, select . Test Mean. from the . LOS . pull-down menu and enter value for mean under the null hypothesis,17.0 in this example.

We illustrate comparisons among several samples using case study 5.1.1. For doing the analysis in JMP, the data needs to be organized in two columns, one column containing the response variable (Y) and another column containing the group label (X).

Below the graph you will see a box labeled, “t Test”. The test statistic is called the t Ratio. For this test, its value is 1.831802, below that is the degrees of freedom, which is calculated as the number of observations – 2. Since our file contained 22 observations, DF = 20 in this case. Finally, you can find the p value is equal to 0.0819.

The test is: JMP gives four different tests for examining the equality of population variances. To use the results of these tests simply examine the resulting p-values. If any/all are less than .10 or .05 then worry about the assumption of equal variances and use the unequal variance t-Test instead of the pooled t-Test.
