The mode of 3,6,9,12,15,18,21,24 is
Answers
Mean :
step 1 Address the formula, input parameters & values.
Formula:
µ =
n
∑
i = 0
Xi
n
Input parameters & values
x1 = 3; x2 = 6, . . . . , x9 = 27
number of elements n = 9
Find sample or population mean for 3, 6, 9, 12, 15, 18, 21, 24 & 27
step 2 Find the sum for dataset 3, 6, 9, 12, 15, . . . . , 24 & 27
µ =
n
∑
i = 0
Xi
n
=(3 + 6 + 9 + . . . . + 27)
9
step 3 Divide the sum by number of elements of sample or population
=135
9
= 15
Mean (3, 6, 9, 12, 15, . . . . , 24, 27) = 15
15 is the mean for dataset 3, 6, 9, 12, 15, . . . . , 24 & 27 from which the standard deviation about to be measured to estimate the common variation of the sample or population dataset from its central location.
Median :
step 1 To find Median, arrange the data set values in ascending order
Data set in ascending order : 3, 6, 9, 12, 15, 18, 21, 24, 27
step 2Since the total number of elements in the dataset is 9 (ODD number), the 5th element 15 is the median for the above data set.
Median = 15
Mode :
step 1 To find Mode, check for maximum repeated elements in the asending ordered dataset 3, 6, 9, 12, 15, 18, 21, 24, 27
