Suppose a data set represents the heights of different towers. The mean of this data set gives an idea of a typical height. Calculating the mean could be seen as rearragning the blocks so that all the towers have the same height.
After the blocks are rearranged, the towers each have a height of Therefore, the mean is If the heights are written as , then the mean is sometimes written as The towers' mean height can then be written as
Find the mean, median and the mode for the following data.
There isn't anything Benji loves more than a bumble bee. Every day he keeps track of how many he sees. The data below gives the number of bumble bees Benji saw for the first days in April. On the th day, Benji sees bumble bees! Determine how this value affects the mean, median and mode of the data.
To begin, we should notice that bumble bees is significantly higher than the number of bees Benji saw on any other day. Thus, is probably an outlier. To see how this outlier affects the measures of center, we can calculate all three with and without the outlier.
