Clues
- -symmetrical about the mean - this symmetry means that the mean, mode, median are all the same - 95% of values are within +- 2 standard deviations of mean - almost all 99.8% of values are within +- 3 standard deviations of mean. page 38 (6, 12)
- a table that shows you how many of each value there are. you must use tallies so you dont make mistakes page 24 (9, 6)
- can be used to compare data sets page 31 (8, 3, 6)
- from bar chart to pie chart pie chart to bar chart page 34 (12, 4)
- is like a bar chart but with lines. show frequency distributions for DISCRETE data. page 35 (8, 4, 5)
- made from 2 bar charts (sideways) that are back to back so you can compare the data they show. page 40 (10, 8)
- show proportions in the data page 32 (9, 3, 6)
- show shapes of distributions. can have unordered and ordered read question for what it wants. can compare two sets of data back to back. page 39 (5, 3, 4, 8)
- simplifing tables makes it easier to pick out useful infomation. easiest way of simplifing is totalling page 28 (10, 6)
- use areas. size of pie chart matters!!!! page 33 (11, 3, 6)
