    To find the mean (average) you must first add all the numbers together.  Your sum should be 724.  Then you divide by the number of scores (8).  The Mean is 90.5

    The median is the middle number.  List the scores from smalles to greatest count from each end into the middle.  The two middle numbers are 91 and 93.  Add these numbers together and divide by 2.  The Median is 92.

    To find the range simply subtract the lowest number from the highest number.  98-82.  The range is 16

    Your range is the lowest number to the highest number, so 82 to 98.

    Your median is the middle number, so 93.

    Your mean is 90.5

     Hope this helps!
