What is Mean (93, 97, 99, 95, 87, . . . . , 93, 92)?

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 93, 97, 99, 95, 87, 96, 100, 99, 93 and 92 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 = 87; x₂ = 92, . . . . , x₁₀ = 100
number of elements n = 10
Find sample or population mean for 93, 97, 99, 95, 87, 96, 100, 99, 93 & 92

step 2 Find the sum for dataset 93, 97, 99, 95, 87, . . . . , 93 & 92

µ = n ∑ i = 0 X_in
= (87 + 92 + 93 + . . . . + 100)/10

step 3 Divide the sum by number of elements of sample or population
= 951/10
= 95.1
Mean (93, 97, 99, 95, 87, . . . . , 93, 92) = 95.1

95.1 is the mean for dataset 93, 97, 99, 95, 87, . . . . , 93 & 92 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 : 87, 92, 93, 93, 95, 96, 97, 99, 99, 100

step 2Since the total number of elements in the dataset is 10 (EVEN number), the median is the average of 5^th and 6^th elements (two middle numbers) for the above dataset.
Therefore,
95 + 96/2= 95.5
Median = 95.5

Mode :
step 1 To find Mode, check for maximum repeated elements in the asending ordered dataset 87, 92, 93, 93, 95, 96, 97, 99, 99, 100
Most repeated element : 93 & 99
Mode = 93 & 99
