Question Video: Using the Mode to Find the Missing Value in a Set of Data Mathematics • First Year of Preparatory School

Video Transcript

Elizabeth has the following data: three, six, four, five, and 𝑚. If the mode is six, find the value of 𝑚.

We know that the mode of any set of data is the value that appears most often. In this set of data, Elizabeth has the numbers three, six, four, five, and the missing number 𝑚. We are also told that the mode is six. This means that the most popular, or most common, number is six. As three, four, five, and six all appear once at present, the only way that the mode can be six is if the missing number 𝑚 is six. The set of data three, six, four, five, and six will have a mode of six. It is usually very straightforward to find a missing number in a data set when given the mode.
