Question

Find the mean, median and mode of the weights of the people shown.

 

 

105kg  53kg  76kg  91kg  120kg  61kg  55kg  98kg  61kg

Answer 1

To find the mean you take the arithmetic average.  Add the weights together and divide the sum by nine.

 

To find the median, put the weights in order from least to greatest.  The number in the center, since there

are an odd number of data points, is the median

 

To find the mode just look for the data point that shows up the most times.  There is only one weight that

is in the list more than one time.. that weight is the mode
