(a)no mode
(b)mean= 4
(c)median= 4
Step-by-step explanation:
the measure of centre are the mode, mean and median
mode: this is the heighest occuring number or the number with the heighest frequency.
mean: this is the average number. it's obtained by adding the data values in a set of numbers and dividing the sum by the number of data items.
meadian: this is the middle number when the data is ordered or when the data is arranged in ascending or descending order.
from the data,
mode: no number occured more than the other. therefore, there is no mode
mean = 1+2+3+4+5+6+7 = 28/7= 4
median= 1,2,3,4,5,6,7
the middle numbers is 4
