Across
- 1. from smallest to largest
- 5. data that has been collected second-hand (by someone else)
- 12. table used to organise data by recording the number of times each data value occurs
- 13. the middle value of a set of data when the data is arranged in order from smallest to largest
- 14. describes data that takes on exact values that may be counted; for example, the number of televisions sold each week
- 17. graph in which equal width columns are used to represent the frequencies (numbers) of different categories

Down
- 2. consists of a horizontal axis labelled and evenly scaled, with each data value represented by a dot
- 3. the difference between the largest and smallest data value
- 4. information collected from surveys
- 6. from largest to smallest
- 7. the most common value in a set of data
- 8. graph drawn in a similar way to a column graph, with horizontal bars instead of vertical columns.
- 9. data that can be measured with a numerical value
- 10. a symbol in an equation or expression that may take many different values (data)
- 11. a measure of the centre of a set of data. If the total value of all the observations is shared equally among all of the values in the data set
