Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In a strongly skewed distribution, the best indicator of central tendency is usually the
A
mean
B
median
C
mode
D
standard deviation
Explanation: 

Detailed explanation-1: -The median is the most informative measure of central tendency for skewed distributions or distributions with outliers. For example, the median is often used as a measure of central tendency for income distributions, which are generally highly skewed.

Detailed explanation-2: -For distributions that have outliers or are skewed, the median is often the preferred measure of central tendency because the median is more resistant to outliers than the mean.

Detailed explanation-3: -In skewed distributions, the median is the best measure because it is unaffected by extreme outliers or non-symmetric distributions of scores.

Detailed explanation-4: -Mean is generally considered the best measure of central tendency and the most frequently used one.

Detailed explanation-5: -The median is usually preferred to other measures of central tendency when your data set is skewed (i.e., forms a skewed distribution) or you are dealing with ordinal data. However, the mode can also be appropriate in these situations, but is not as commonly used as the median.
