Calculating Rates

The basic formula for calculating rates is the number of times something actually happened/the number of times it could have happened.

Measures of Central Tendency Mean:

𝐴𝑣𝑒𝑟𝑎𝑔𝑒 (𝑀𝑒𝑎𝑛) = 𝑆𝑢𝑚 𝑜𝑓 𝑎𝑙𝑙 𝑡ℎ𝑒 𝑣𝑎𝑙𝑢𝑒𝑠

𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑎𝑙𝑙 𝑡ℎ𝑒 𝑣𝑎𝑙𝑢𝑒𝑠 𝑖𝑛𝑣𝑜𝑙𝑣𝑒𝑑

Median: The midpoint (center) of the distribution of values, or the point above and below which 50 percent of the values fall . The median is a data point on the number line. Mode: The value that occurs most frequently in the data. The mode appears as a data point on the number line. Variance:

𝑠2 = Σ(X − �̅�)2

𝑁 − 1

Standard Deviation:

𝑆𝐷 = √ ∑( X − x̄)

(N − 1)
