23.1 Median and mode
Median and Mode
Find out how to calculate the median and mode of any data set, with step-by-step examples for odd, even, and tied values.
What You'll Learn
Order a data set from least to greatest before locating the median.
Identify the middle value for an odd number of data points as the median.
Average the two middle values for an even number of data points to find the median.
Recognize the mode as the value or values that appear most often in a data set.
Classify data sets as having no mode, one mode, or multiple modes (bimodal or multimodal).
Compare median and mode to decide which measure better describes a data set with repeated or extreme values.
What You'll Practice
1
Finding median and mode from lists of numbers
2
Calculating median from frequency tables showing product sales
3
Determining median when given an even number of data values
4
Solving problems where median is known and missing data must be found
Why This Matters
Median and mode are essential statistics you'll use throughout math and science to analyze real data. Whether you're interpreting test scores, sales figures, or survey results, these measures help you understand what's typical in a data set and make informed decisions.
