What is Mean (11.2, 11.2, 11.3, 11.35, 11.2, 11.15, 11.2, 11.1)?

The below workout with step by step work help grade school students or learners to understand how to find what is the mean or average for data set 11.2, 11.2, 11.3, 11.35, 11.2, 11.15, 11.2 and 11.1 to measure or locate the center point of sample or population data which involved in the statistical survey or experiment, to draw conclusions of sample or population data characteristics.
Mean :
step 1 Address the formula, input parameters & values.
Formula:

µ = n ∑ i = 0 X_in
Input parameters & values
x₁ = 11.1; x₂ = 11.15, . . . . , x₈ = 11.35
number of elements n = 8
Find sample or population mean for 11.2, 11.2, 11.3, 11.35, 11.2, 11.15, 11.2 & 11.1

step 2 Find the sum for dataset 11.2, 11.2, 11.3, 11.35, 11.2, 11.15, 11.2 & 11.1

µ = n ∑ i = 0 X_in
= (11.1 + 11.15 + 11.2 + . . . . + 11.35)/8

step 3 Divide the sum by number of elements of sample or population
= 89.7/8
= 11.2125
Mean (11.2, 11.2, 11.3, 11.35, 11.2, 11.15, 11.2, 11.1) = 11.2125

11.2125 is the mean for dataset 11.2, 11.2, 11.3, 11.35, 11.2, 11.15, 11.2 & 11.1 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 : 11.1, 11.15, 11.2, 11.2, 11.2, 11.2, 11.3, 11.35

step 2Since the total number of elements in the dataset is 8 (EVEN number), the median is the average of 4^th and 5^th elements (two middle numbers) for the above dataset.
Therefore,
11.2 + 11.2/2= 11.2
Median = 11.2

Mode :
step 1 To find Mode, check for maximum repeated elements in the asending ordered dataset 11.1, 11.15, 11.2, 11.2, 11.2, 11.2, 11.3, 11.35
Most repeated element : 11.2
Mode = 11.2
