Introduction:  Golden State Warriors selected stats 2016/2017 regular season is the data i used, I pulled this data from statcrunch.  The sample size is 12, the first quantitative variable is (PTS) points score durnig the game and the second quantitative variable is (FT%) Free throws precentages.

Analysis:The regression equation is 65.093695+0.90831867x.The correlation coefficient is 0.70330594. The coefficient of determination is R-sq. = 0.49463924. The linear relationship is strong because it is between .70 to .84 and this is considered to be a strong positive. The coefficient of determination is 0.7033 which means that 70.33% of the change in Y is determined by the regression equation.

Conclusion: Golden State Warriors selected stats 2016/2017 regular season data was used to obtain the sample size of 12.  The dependent X variable was the (PTS) points score, and the independent Y variable was the (FT%) Free throws precentages. A regression should be done because the correlation coefficient is 0.7033 and the points on the scatterplot are  somewhat scattered and cluster about the regression line and about 70% of the change in y is explained by the regression equation. Therefore, a linear regression should have been completed on this data.
