1. Statistics for Science

2. Mean (aka average… it’s a super nice guy
Mean (aka average… it’s a super nice guy!) add all observed values and divide by the number of observations to calculate what an average observation of that data set would be.

3. M
Median the central value of a set of observed. If there’s an even # of observations, take the middle 2 and divide by 2 If there’s an odd # of observations, take the exact middle number.

4. Mode the observation that is seen with the most frequency.

5. R
Range the difference between the highest and the lowest observed value. Version 1: range = 8 (subtract highest from lowest value) Version 2: range = (writes the actual lowest and highest value to “bookend” the range

6. Standard Deviation measures the average dispersion, or average spread, of your data set around your mean. A smaller Stdev is better!! S
