Question

Find The Mean, Median, Mode,Range of each set of data.

(a)61,57,49,60,45,51,57,60,53,57,55,48,65,52​

Answer 1

$\huge\boxed{\fcolorbox{cyan}{red}{Answer}}$

Mean = sum of the numbers/total number of numbers = 805/15=161/3=53.66

Arrange the in ascending order:45,45,48,49,51,52,53,55,57,57,57,60,60,61,65.

The middle most number is 55.So Median = 55

55 As 57 occurs maximum number of times so mode = 57.

57.Range = highest value-lowest value

= highest value-lowest value= 64-45 = 20.

Answer 2

Mean = sum of the numbers/total number of numbers = 805/15=161/3=53.66

Arrange the in ascending order:45,45,48,49,51,52,53,55,57,57,57,60,60,61,65.

The middle most number is 55.So Median = 55

55 As 57 occurs maximum number of times so mode = 57.

57.Range = highest value-lowest value

= highest value-lowest value= 64-45 = 20.
