Topic 1 - Data, Statistics and Jamovi Flashcards
What are the 2 numerical data types?
- Continuous
- Discrete
What are the 2 categorical data types?
- Ordinal
- Nominal
What is continuous data?
A continuum of variables is possible e.g. height
What is discrete data?
Can only be discrete values e.g. number of siblings
What is ordinal data?
Categories that have order e.g. size.
remember - ordinal you need to make sure everyone would agree with the same ordering
What is nominal data?
Categories with no order e.g. hair colour
Histograms are used to show…
Distribution of variables
Bar charts are used to…
Compare variables
When you have 1 variable and are using categorical data, what chart would you use to display ordinal data?
Bar chart
When you have 1 variable and are using categorical data, what chart would you use to display nominal data?
Pareto chart
When you have 2 variables which are both categorical, which chart/s would you use to display data?
- Clustered bar chart
- Stacked bar chart
Which type of graph would you use to display nominal data?
Pareto chart:
*in order of counts because no natural order exists
Which type of graph would you use to display ordinal data?
Bar chart
When you have large numbers and variables close together you should use a…
Histogram
Which type of graph would you use to display data with a discrete variable?
- Bar chart
- if there are a small number of discrete values; bar chart*
- Histogram
- if there are a large number of discrete values closer to continuous; histogram
Which type of graph would you use to display data with a continuous variable?
- Histogram
- Boxplot
Which type of graph would you use to display data with two categorical variables?
- Clustered bar chart
- Stacked bar chart
Numerical data has to have…
Numbers
Continuous data has … answers
Infinite possible
Length is categorised into which type of variable?
Continuous
Colour is categorised into which type of variable?
Nominal
can’t order colours
Brightness is categorised into which type of variable?
Ordinal
e.g. bright, very bright, etc.
Weight is categorised into which type of variable?
Continuous
unless a set weight is used for something, it can be ordinal
