okay, i have found the:
mean:77
mode:71
median:77
range:49
1st quartile: 65
3rd quartile: 90.5 
Can someone help me find what the variance is and what is the standard deviation of the scores?

But you didn't give the scores.  We have to have the scores in order
to calculate the variance and standard deviation.
