For the numbers 4 6 9 2 9 find the Median the mode the mean
For the numbers 4, 6, 9, 2, 9, find: the Median, the mode, the mean, the range, the population variance, the population standard deviation.
Solution
numbers in ascending order = 2 , 5 , 7 , 8 , 8
median = 7 (middle element)
mode = 8 (most repeated number)
mean = 1/5(2+5+7+8+8) = 6
range = max - min = 8 - 2 = 6
population variance = (1/5)*((2-6)^2+(5-6)^2+(7-6)^2+(8-6)^2+(8-6)^2) = 5.2
population standard deviation = sqrt(variance) = sqrt(5.2) = 2.28035
