Statistical Test Decision Tree Flashcards

Vocabulary flashcards covering the statistical test decision tree, including criteria for choosing paired samples and independent samples t-tests based on experimental design and sample sizes.

Statistical Test Decision Tree

A flowchart used to select the appropriate statistical t-test based on experimental design, presence of matching or pairing, and sample size.

Decision Tree Application Criteria

Criteria specifying that the decision tree should be used when given two correlated groups, two related groups, or a repeated measures design with two observations from each participant.

Paired Samples T-Test

The statistical test selected in the decision tree when a study has a within-subjects design.

Independent Samples T-Test

The statistical test selected when a study does not have a within-subjects design, but does feature matching or pairing.

Large Independent Samples T-Test

The statistical test selected when there is no within-subjects design, no matching or pairing, and both sample sizes are greater than or equal to $30$ ($n_1, n_2 \ge 30$).

Sample Size Criterion ($n_1, n_2 \ge 30$)

The question in the decision tree asking if both sample sizes are greater than or equal to $30$ ($n_1, n_2 \ge 30$) to determine the choice of statistical test when no matching or pairing is present.
