(Test for Homogeneity)

1. Count Condition: The data are counts.

2. Independent Condition: Data in groups are independent.

3. Large sample

Two Sample Proportions

(Independent)

1. Randomization Condition: Samples in each group are random samples (SRS) or representatives of their populations or in experiments the treatments are randomly assigned.

2. Normality Condition: n1p1 and n2p2 ≥ 10 and n1q1 and n2q2 ≥ 10.

3. Independent Condition: The selection of each subject is independent of each other (10n < N) for each sample. In some experiments this is not necessary.

4. Independence of Groups Condition: The groups are independent of each other.
