Mean median mode

Question 1

Three type of relationship on the basis of skewness of the data

Answer 1

1.) Symmetric distribution
2.) Positively skewed distribution
3.) Negatively skewed distibution

Question 2

Mean mode median formula

Answer 2

Mean−Mode=3(Mean−Median)

Question 3

Symmetric distribution
(relation between mean, median, mode
and also example)

Answer 3

Mean = Median = Mode
Example: Normal Distribution

Question 4

Positively skewed distribution
(another name and relation between mean, mode, median)

Answer 4

Mean > Median > Mode
The right tail is longer (more extreme values on the right).

Question 5

Negatively skewed distribution
(another name and relation between mean, mode, median)

Answer 5

Negatively Skewed (Left-Skewed) Distribution:

Mode > Median > Mean
The left tail is longer (more extreme values on the left).
