Explanation:

Mean :

STEP 1 Address the FORMULA, input parameters & values.

Formula:

µ =

n

∑

i = 0

Xi

n

Input parameters & values

x1 = 1; x2 = 3, . . . . , x6 = 11

number of elements n = 6

Find sample or population mean for 1, 3, 5, 7, 9 & 11

step 2 Find the sum for dataset 1, 3, 5, 7, 9 & 11

µ =

n

∑

i = 0

Xi

n

=(1 + 3 + 5 + . . . . + 11)

6

step 3 Divide the sum by number of elements of sample or population

=36

6

= 6

Mean (1, 3, 5, 7, 9, 11) = 6

6 is the mean for dataset 1, 3, 5, 7, 9 & 11 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 : 1, 3, 5, 7, 9, 11

step 2Since the total number of elements in the dataset is 6 (EVEN number), the median is the average of 3rd and 4th elements (two middle numbers) for the above dataset.

Therefore,

5 + 7

2

= 6

Median = 6

Mode :

step 1 To find Mode, check for maximum repeated elements in the asending ordered dataset 1, 3, 5, 7, 9, 11

No mode available for the above dataset
