How do you find the median of a data set?

Back

To find the median, arrange the numbers in ascending order and identify the middle number. If there is an even number of values, the median is the average of the two middle numbers.

What is the mode of a data set?

Back

The mode is the number that appears most frequently in a data set. A data set may have one mode, more than one mode, or no mode at all.

Can a data set have more than one mode?

Back

Yes, a data set can have multiple modes if two or more numbers appear with the same highest frequency.

Front

What is the difference between mean and median?

Back

The mean is the average of all numbers, while the median is the middle value when the numbers are sorted. They can differ significantly, especially in skewed distributions.

What is a skewed distribution?

Back

A skewed distribution is one where the values are not symmetrically distributed, causing the mean and median to differ.

Front

How can outliers affect the mean?

Back

Outliers can significantly affect the mean by pulling it in their direction, making it higher or lower than the central tendency of the rest of the data.

Front

What is the importance of understanding measures of central tendency?

Back

Understanding measures of central tendency (mean, median, mode) helps summarize and interpret data, making it easier to analyze and draw conclusions.
