Explanation / Answer

Central tendency:

Mean(X1)=72.91                        Mean(X2)=46.69
medain (X1)=72.5                       medain (X2)=49
mode(x1)=79                            mode(x2)=48

Measure of varaince:
Range(X1):49                                                         Range(X2):42
variance(X1): 147.81                                              variance(X2):101.67
standard deviation(X1):12.15                                    standard deviation(X2):10.08

measure of position:

Q1(X1)=66.5               Q1(X2)=42.5
Q2(X1)=72                   Q2(X2)=48
Q3(X1)=79                   Q2(X2)=53.5

Correlation(X1,X2)=0.7142
