Answer:
mean = 78.4
median = 77.5
mode = 75
This is Right - skewed (positive skewness) distribution
Step-by-step explanation:
Mean:-
The mean (average) is found by adding all of the numbers together and dividing by the number of items and it is denoted by x⁻
mean = [tex]\frac{64+80+75+98+75}{5}[/tex]
mean (x⁻ ) = 78.4
The mean of the given data = 78.4
Median:
The median is found by ordering the set from lowest to highest and finding the exact middle.
64 ,75, 80, 98
The middle term of the given data set = [tex]\frac{75+80}{2} =77.5[/tex]
Mode :
The mode is the most common repeated number in a data set.
64 ,75, 75, 80, 98
in data the most common number = 75
Conclusion:-
mean = 78.4
median = 77.5
mode = 75
This is Right - skewed (positive skewness) distribution
