Solution
Mean = `"Sum of observation"/"Total number of observation"`
Sum of observation = 1 + 3 + 3 + 4 + 5 + 6 + 97 = 119
Total number of observation = 7
Mean = `119/7`
= 17
Median = `(n + 1)/2`
= `(7 + 1)/2`
= `8/2`
= 4th term
Median = 4
Hence, Mean = 17 and Median = 4
Median describes the set of numbers better.
