2. Suppose in a given week, the number of
persons who rode the Vikings was
recorded as follows:
1,187, 1,205, 1,196, 1,212, 1,192, 2,202,
and 2,194. What was the average
number of persons who rode per day
during the given week?
3. SIMPLE AVERAGE
The resulting number when the sum of a set of
numbers is divided by the number of addends;
also called the arithmetic mean.

𝑡ℎ𝑒 𝑠𝑢𝑚 𝑜𝑓 𝑎 𝑠𝑒𝑡 𝑜𝑓 𝑛𝑢𝑚𝑏𝑒𝑟𝑠
𝑡ℎ𝑒 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑎𝑑𝑑𝑒𝑛𝑑𝑠

8. WEIGHTED AVERAGE
The resulting number when the sum of the products of
each number in a set and the number’s corresponding
weight is divided by the sum of the weights.
