1.

The mean can be found by adding up each value and dividing by the number of values. The mean is the middle value when the values are put in order.

2.

The 5 number summary is the following: the minimum value, the 1st quartile, the median, the 3rd quartile, and the maximum.

The 1st quartile is the median of all values less than the median. Similarly, the 3rd quartile is the median of all values greater than the median.
