Answer 1

Answer:

Step-by-step explanation:

ANSWER

A distribution in which the values of mean, median and mode coincide (i.e. mean = median = mode) is known as a symmetrical distribution. Conversely, when values of mean, median and mode are not equal the distribution is known as asymmetrical or skewed distribution. In moderately skewed or asymmetrical distribution a very important relationship exists among these three measures of central tendency. In such distributions the distance between the mean and median is about one-third of the distance between the mean and mode, as will be clear from the diagrams 1 and 2. Karl Pearson expressed this relationship as:

Mode = mean - 3 [mean - median]

Mode = 3 median - 2 mean

3 Median = Mode + 2 Mean

Answer 2

Answer:

2Mean

Step-by-step explanation:

As we know that,

=>3 Median= Mode + 2Mean

=>3 Median-Mode=2Mean

This is done by empirical relationship between the three measure of Central tendency
