Roulette 1 N=1 I set n=1 for this graph. This graph does not follow the normal quantile plot. The normal quantile plot does not have a straight line. The graph is skewed to the right. This graph is positively skewed. The skewness value is 5.73. The normal and smooth lines do not follow each other. The kurtosis for this graph is 31.06-this is way over zero. The closer to zero the kurtosis is the more normal curve. Ideally, the kurtosis is going to be in between -0.1 to 0.1. Out of all my graphs this n value leads to worst kurtosis and least normal curve. N=50 I set n=50 for this graph. This graph follows the normal quantile plot more than the previous graph. The normal quantile plot looks like it is beginning to have a straight line. The outlier box has a large outlier on the right side. The graph is skewed to the right. This graph is positively skewed. The skewness value is 0.822. The normal and smooth lines do not follow each other. The kurtosis for this graph is 0.84-this is still over zero. The closer to zero the kurtosis is the more normal curve. Ideally, the kurtosis is going to be in between -0.1 to 0.1. Setting n=50 is helping my graph have a normal curve. N=1000

I set n=100 for this graph. This graph follows the normal quantile plot more than the previous graph. The normal quantile plot looks like it has a straight line. The outlier box has outliers on both the right and left side. The skewness value is 0.28.The normal and smooth lines follow each other to a certain extent. The kurtosis for this graph is 0. 30- this is still over zero but is much closer to zero than the previous two graphs. The closer to zero the kurtosis is the more normal curve. Ideally, the kurtosis is going to be in between -0.1 to 0.1. Setting n=1000 has a relatively normal curve. For roulette 1 n=100 is the most ideal for achieving a normal curve
Roulette 2 N=50 I set n=50 for this graph. This graph follows the normal quantile plot to a certain extent. The normal quantile plot is a straight line. The outlier box has outliers on both the right side. The data is skewed to the right. The graph is positively skewed. The normal and smooth lines follow each other to a certain extent. The smooth curve has some waves indicating that the curve does not look normal. The kurtosis for this graph is -0.12. This kurtosis is within the ideal recommendation. The closer to zero the kurtosis is the more normal curve. Ideally, the kurtosis is going to be in
