Question

Which combination would lead you to Fail to Reject H₀?

Correlation: r_obt = 0.68 r_crit = 0.64

ANOVA: F_obt = 3.61 F_crit = 2.55

Chi-Square GOF: χ²_obt = 3.24 χ²_crit = 4.25

2-tailed t-test: t_obt = 2.36 t_crit = 1.89

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
