Answer:
I will suppose data here ,when you run your you just need to use your own statistics data for mean ,median, variance and standard deviation
data1 = {1, 3,4,7,12,3,45}
x = np.arange(20)
print("Your Team's Relative skill in 2013 to 2015")
print("descriptive statistics including the mean, median, variance, and standard deviation for the relative skill of your team")
mean = your_team_df['elo_n'].mean(data1)
median = your_team_df ['elo n'].median(data1)
variance = your_team_df ['elo n']. tvar(x)
stdeviation = your_team_df ['elo n'].stdev(data)
print('Mean =' , round(mean, 2))
print('Median =' , round(median, 2))
print('variance =' , round(variance, 2))
print('Standard deviation =' , round(stdeviation, 2))
