Correlation

The correlation is commonly used and a useful statistic used to describe the degree of the relationships between two or more variables. Pearson's correlation reflects the degree of linear relationship between X variables which are independent and a Y variable which is independent and it ranges from positive 1 to negative 1 (+1 to -1). Below are statistics I have managed to gather which shows the relationship between the variables of wfood,  totexp, income, age, nk.

The Null Hypothesis - H0: Correlation has risen by chance i.e. r = 0

The Alternative Hypothesis - H1: Correlation has not risen by chance i.e. r ≠ 0

*Exception: Reject H0 when P-value ≤ α = 0.05

Correlations: wfood, totexp, income, age, nk
