Find the mean, the median and the mode of the temperatures on the 10 rainy days.

The month, in degrees Celsius: $31, 32, 30, 33, 34$, $33, 31, 29, 28, 30$, $32, 33, 35, 34, 32$, $31, 30, 29, 28, 27$, $29, 31, 32, 33, 31$, $30, 28, 27, 29, 30$. It rained on days $8, 9, 10$, $17$ to $20$ and $27$ to $29$. The mean is the total divided by how many values there are. Total = mean $\times$ count. The median is the middle value of the sorted list. With an even number of values, it is halfway between the two middle ones. The mode is the value that appears most often. It works for words too.
