They should study and be able to find the following in a set of data:
- Frequency- the number of time a response occurs.
- Cumulative Frequency- the running total of frequencies.
- Mean- the average of a set of data. You find the mean by adding up the numbers and dividing by the number of addends.
- Mode- the number that occurs most often in a set of data. There may be more than one mode or no mode.
- Median- the middle number. Put the numbers in order from least to greatest, then cross them out on each end until you find the number in the middle. If there are two middle numbers, then find the middle of those numbers.
- Line Plot- a graph that shows the frequency of data along a line.
- Range- the difference between the greatest and least numbers in a set of data.
- Outlier- a value separated from the rest of the data. (Ages in our class, everyone was 9-10, and Miss Zelle's age was much further, making her an outlier)
- Scale- a series of numbers placed at fixed or equal distances. Ex: 0-20 or 0-50
- Interval- is the difference between two numbers on the scale. Ex: 2's, 5's or 10's
- Study notes and Study guides
