Question 1 Report
The diagram shows seven tiles. Each tile has a number printed on it.
Write down the mode of the numbers on the tiles.
Answer Details
The mode is the value that appears most often in a data set. Here the data are the seven numbers printed on the tiles, so the mode is the number that appears on more tiles than any other.
The number \(5\) appears more often than any other number on the tiles, so the mode is \(5\) [B1].
Two points are worth noting. The mode is the value itself, not how many times it occurs, so an answer giving the frequency does not gain the mark. Also, unlike the mean and the median, the mode does not need the data to be put in order, and it is always an actual member of the data set. If two different numbers had tied for the highest frequency the set would have two modes, and if every number appeared once the set would have no mode at all.
