Answer:
Mean = 25
Median = 23
Mode = 33
Explanation:
First, let's write out all the values represented in the stem and leaf plot. We have the following data sets as follows:
15, 18, 18, 19,
22, 23, 25,
31, 33, 33, 33
=>Mean = sum of all values ÷ no of values
= (15+18+18+19+22+23+25+31+33,+33+33)/11
= 270/11 ≈ 25 (to the nearest whole number)
=>Median is the middle value when the data set is ordered. Since we have 11 values, our median value would be the 6th value in our data set = 23
15, 18, 18, 19, 22, |23|, 25, 31, 33, 33, 33
=>Mode is the most occured value = 33
