A researcher conducts an RCT to evaluate a financial literacy nudge with 400 subjects randomly assigned: 200 in the Treatment group, and 200 in the Control group. To build a balance table, the researcher checks two baseline variables: Variable 1 (Age - a continuous variable: Treatment Mean = 24.5, Control Mean = 23.8) and Variable 2 (Gender - a binary Female yes/no variable: Treatment = 55% female, Control = 48% female). Which statistical test should the researcher use for each variable to verify the groups are balanced?
A
Variable 1 (Age): T-test, because it compares means of a continuous variable; Variable 2 (Gender): Chi-Square test, because it compares proportions of a binary/categorical variable.
B
Variable 1 (Age): Chi-Square test; Variable 2 (Gender): T-test.
C
Both variables: T-test, because the two groups are equal in size.
D
Both variables: Chi-Square test, because both compare a Treatment group against a Control group.
