Discussion and justification based on r only is not sufficient. Correlation = 0.96 There appears to be a linear trend between the two variables. As the data points are relatively close to the regression line‚ it can be stated that there is strong positive association between chest and weight. The correlation coefficient of 0.96 (very close to 1) confirms that the linear relationship is very strong and positive. Model obtained‚ equation specified in context and prediction made in context
