Stats Study Notes
Statistics- Data used to make judgment (decision) about a situation
1. Descriptive - Polls and Survay
- Correlation
2. Inferential -Cause and effect relationships
Population > Parameter
Sample> Statistic
4 Levels of measurement
1. Nominal - (catigories, can only measure frequency)
2. Ordinal - Data is ranked (1st 2nd 3rd ) Don’t know how far they are from each
other, first might be 4 seconds and second might be 4.1 seconds or 10seconds
we don’t know we only know where it is in relation to other scores)
3. Interval- Equal points or units of measurement assigned but 0 is a value, so
therefore things cant be proportional. Ex tempature
4. Ratio- Measures the distance from 0 (zero means nothing) therefore
comparisons can be made, ex 50kg is half of 100kg. Weight, distance
Independent Variable- The one that is controlled or manipulated
Dependant- The one we see how it is effected
Frequency Distribution-
Ungrouped- each value has its own group (frequency of 1, 5 times/ frequency of
2 3 times/ frequency of 3 9 times)
Grouped- Values are put into intervals (frequency of 1-3, 17 times. Frequency of
4-6 10 times)
Making intervals
- Find N of scores
- Look up #of intervals for that N on the chart
- i=(biggest value- smallest value)/ # of i
Shapes of Curves
Normal Distribution = Bell curve (mean = median= mode)
Bimodal= 2 modes (usally when you have 2 characteristics )
