In today’s video, we will go through the process conducting a paired samples (or dependent samples) t-test in SPSS. Let’s get started! Research Scenario. First let’s look at a research scenario. In this situation, we are interested in testing the effectiveness of an after-school math program for 5th graders. We administer a pretest to 12 ...

A second t-test, appropriate for comparing paired (dependent) samples, is introduced. Sirkin, Statistics for the Social Sciences, pp. 271-296. Testing Hypotheses about Differences among Several Means. The techniques for testing hypotheses covered thus far are limited to comparisons of two subsamples. When the situation calls for comparison of ...

Even if data are related in pairs, sometimes the paired t is still inappropriate . Here's a simple rule to determine if the paired t must not be used - if a given data point in group one could be paired with any data point in group two, you cannot use a paired t test . Hypothesis takes the form Ho: µ1 = µ2. If comparing multiple groups use ...

Recall that the paired t-test for the mean difference is actually just a one-sample t-test performed on the differences. So the TI for a one sample t-test in Chapter 10 will apply again. If you enter the paired observations into two columns (for example, L1 and L2), then you will first need to compute the differences using a linear transformation.

(A) The test was statistically significant because a p-value of 0.24 is greater than a significance level . of 0.05. (B) The test was statistically significant because p = 1 – 0.24 = 0.76 and this is greater than a significance level of 0.05. (C) The test was not statistically significant because 2 times 0.24 = 0.48 and that is less than 0.5.

PAIRED SAMPLES T-TEST. Paired Samples T-Tests: Are also known as Dependent or Matched T-Tests. Do not utilize population parameters, rather are a comparison of scores from a single sample measured across time. Look for key words such as “Test-retest”; “Pre-Post”; “Same individuals tested” ( = 0. Equations: df = N - 1. Confidence ...

Comparison of two means (dependent): If your design has paired observations (e.g. before-and-after), then what seems to be a two-group test is really just a one-group test of whether the average change is different from zero. (See paired t-test in the Analysis II Module).
