Step 1
Given the information below, 12,17,18,2,19,20,15,22,16,8,20,23,11,25,9
Formula for Mean is,
Mean=Sum of all observationsnumber of observations
=12+17+18+2+19+20+15+22+16+8+20+23+11+25+915
=23715
=15.8
Hence, Mean is 15.8.
Step 2
The first step is to organize the data in ascending order using the formula for the median.
2,8,9,11,12,15,16,17,18,19,20,20,22,23,25
Therefore,
Median=(n+12)th observations
=(15+12)th observations
=8th observation
=17
The median of the data is therefore 17.
Mode is expressed as,
Mode=Maximum repeated observation
Mode=20
Therefore, the Mode of the provided data is 20.
