Attitude towards staying active was measured by asking a series of questions regarding perceptions towards physical activity, resulting in a "positive attitude" or "negative attitude" classification. General activity level was classified as active, mildly active, and inactive. What is the degrees of freedom for the Chi-square test for an association between attitudes and physical activity level

Answer 1

degree of freedom is 2

Step-by-step explanation:

Physical activity classified as "positive attitude" or "negative attitude"

General activity level was classified as active, mildly active, and inactive.

Degree of freedom (Row-1)(Column -1) = (2-1)(3-1)=2

Therefore degree of freedom is 2
