1

Define an indépendant variable

The one variable that you change

2

Define a dependant variable

The variable that you measure

3

Define a control variable

Any variable you keep the same to make it a fair test

4

Define directly proportional

If one variable increases the other variable increases at the same rate. eg if x doubles then y must double

5

Define inversely proportional

If one variable increases the other variable decreases at the same rate. eg if x doubles then y must halve

6

Define an anomalous result

An result which does fit the pattern of trend

7

Define interval

The spacing between measurements eg 0, 10, 20, 30 40, 50 cm would have an interval of 10

8

Define range

The maximum and minimum values eg 0, 10, 20, 30, 40, 50 would have a range of 50 - 0 cm

9

Define resolution

The smallest change that can be measured with a particular piece of equipment

10

How can the uncertainty in a measurement be measured?

Half of the range

11

When should you draw a line graph

When both variables are continuous

12

When should you draw a bar graph

If one of the variables is discrete or categoric

13

Define a continuos variable

Can be recored as any number eg time, mass, volume

14

Define a discrete variable

Can be recored only as a whole number eg number of goals in a match

15

Define a catergoic variable

Is recored in words instead of numbers eg colours or types of metal
