Question

Answer 1

Answer:

1 all the numbers are mode

2 median is 56

Step-by-step explanation:

Check whether the data is in ascending order.

Yes

Mode = number that is repeated maximum number of times, all numbers have same frequency 1, so all numbers are mode

Median = it is the number that divides the entire data into two equal half

here total number of observation N = 10

median will be the average of numbers found at N/10 and N/10 + 1 position

it is the 5 th and 6 th position

as per data value at 5 th position is 54 and value at 6 th position is 58

average of these two numbers is (54+58)/2 = 112/2= 56 is the median
