Q: How do you calculate the mean, median, and mode of a data set?
To calculate the mean, you sum all the values in the data set and divide by the total number of values. To find the median, you arrange the data set in ascending order and find the middle value (if there’s an even number of values, it’s the average of the two middle values). The mode is the value that appears most frequently in the data set.
What is the difference between mean, median, and mode?
The mean is the average of all values, the median is the middle value when the data is ordered, and the mode is the most frequently occurring value. Each measures central tendency but can be more appropriate depending on the data distribution and presence of outliers.
When is the median a better measure of central tendency than the mean?
The median is often a better measure of central tendency than the mean when the data set contains outliers or is heavily skewed, as it is less affected by extreme values. For example, in income distribution, the median provides a more representative “typical” income.
Can a data set have no mode?
Yes, a data set can have no mode if all values appear with the same frequency. For example, in the data set {1, 2, 3, 4, 5}, each number appears once, so there is no mode.
