3

## Probability

### 1 (certain) to 0 (impossible) that the results happened because of variability

4

## Magnitude

### < > =

5

## Ratio scale

### Has magnitude, equal intervals, and absolute 0

6

## Interval scale

### Magnitude and equal intervals but no absolute 0

7

## Ordinal scale

### Only magnitude eg. Ranking kids heights from tallest to shortest

8

## Nominal scale

### No magnitude, just categories eg make of a car

9

## Discrete variable

### Can only have a countable number of values between two points (no half values) eg the number between 1 and 3

10

## Continuous variable

### Infinite values between two points eg 1.000002465

11

## Lower real limit

### Any number lower would be rounded out to be a smaller number eg 33.5
