Practice Mode in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The mode is the value or values that appear most frequently in a data set — it is the most common or most popular data value.
The mode is the "most popular" value — if you had to guess one number and wanted to be right as often as possible, pick the mode.
Example 1
easyFind the mode of \{2, 4, 4, 5, 7, 7, 7, 9\}.
Example 2
mediumFind the mode of \{3, 5, 5, 8, 8, 12\}.
Example 3
easyFind the mode of \{1, 3, 3, 3, 5, 5, 6, 9\}.
Example 4
mediumThe data set \{3, 5, 5, 7, 8, x\} has mean 5.5 and mode 5. Find x.
