Calculate the mean, median and range of above data.​

Answer 1

Answer:

Mean = 14.5

Median = 16

Range = 26

Step-by-step explanation:

Mean = sum of all observations/ No. of observations

         =23+24+25+26+27+1+4+9+3+3/10

         =145/10

         =14.5

Median = Middle Value

Ascending Order = 1,3,3,4,9,23,24,25,26,27

                             = 9,23

                             =9+23/2

                             = 32/2

                             = 16

Range = Highest Observation - Lowest Observation

Ascending Order = 1,3,3,4,9,23,24,25,26,27

                             = 27-1

                             = 26
