Statistics can you communicate trends in data. You might find some of the following basic statistics to be helpful in your analysis:
|250 + 300 + 225 = 775|
|775 ÷ 3 = 225 is the mean (or average)|
What is the mean good for?
Sometimes it’s useful to know if something is above or below average.
For example, is your grade above or below the average of the rest of the class?
Mode = the most repeated number or category
The mode is the only measure of average that can be used with nominal data (i.e. categories).
For example, late-night users of the library were classified by faculty as:
The median or mean can not be calculated (what would it it be a bio-soci-sci student?).
The mode is biological science students since they are most common.
What is the mode good for?
Mode could be used for scheduling, what hours are most people buying the product, coming in to the store, calling for help?
The mode is most helpful when a single value is repeated much more often than others.
