- Non-official statistics:
- Produced for non-governmental organisations (e.g. media).

- The number of times something has occurred.
- Ordinal data:
- Data that falls under ordered categories where the distances between the categories are unknown (e.g. eye colour).
Data cont.

- Interval data:
- Incremental quantitative data (e.g. temperature, time).
- Ratio data:
- Like interval data but they start from zero.
- Raw data:
- Data that hasn’t been processed.
Averages
Averages
- Average: a measure of central tendency.
- Mean: an average by adding up the total number and dividing by the number of students for example.
- Median: the middle value when the data is ordered in ascending/descending order.
- Mode: the most common value.
- Standard deviation: a measure of data variation with respect to the arithmetic mean.
Quantitative Data
Quantitative Data
Quantitative data is presented in charts and tables.
Charts and tables
Charts and tables
- Quantitative data is presented in charts and tables.
- Charts have a horizontal axis (x), where the independent variables are inputted.
- The vertical axis (y) depicts the dependent variables.
- Tables are used to present nominal data.
Bar charts
Bar charts
- Bar charts are used to compare categories or the frequency of an occurrence.
- Bar charts usually have gaps between them.
- If a bar chart doesn't have gaps between them, then they are called histograms.
Other charts
Other charts
- Pie charts show the different proportions of various categories.
- Scatter graphs show the relationship between two variables.
- Line graphs show trends in the data.
Patterns and trends
Patterns and trends
- Sociologists try to draw patterns and trends after collating their data.
- To do this, they try to find the relationship between the variables.
- Statistical tests of significance show the probability of a relationship existing between the variables.
