The number of times a specific observation occurs in the collected data is called the…… of value.
a) Frequency
b) Mode
c) Median
d) Mean
Range is………between the largest and smallest values of a data.
a) Difference
b) Addition
c) Multiplication
d) Division
Solution:6, 4, 15, 12, 20, 28, 30, 25, 10, 25
Biggest value = 30 smallest value= 4
Range = 30 – 4 = 26
Find the arithmetic mean of the values
1, 6, 8, 9, 7, 5.
a) 8, 9
b) 5
c) 6
d) 1
Mean of 50, 0, 30, 12
a) 20
b) 21
c) 22
d) 23
Median of the data 4, 5, 7 is
a) 4
b) 5
c) 7
d) None of these
Solution:4, 5, 7 Odd number and already in ascending order. So 5 is median
Mode of the data is 4,5,7,4,8,5,7,1,7
a) 4
b) 5
c) 7
d) 8
Solution: Ascending order 1,4,4,5,5,7,7,7,8
Most frequent value is 7.
