Q

What must figures and tables have?

A

Title
Labelled axes with units
Legend
[Plus: Annotations to describe certain elements, asterisks to denote significance]

2
Q

What must a legend include?

A

Title- descriptive or declarative title
Method of generation (brief, 1 sentence)
Result (brief) explanation, sample size and p values
Definition of symbols/ scale bars/ error bars/ abbreviations

3
Q

What are the types of graph you can use?

A
Pie chart
Bar chart
Histogram
Dot-plot
Box and whiskers
Scatter plot
Line graph 
Cumulative frequency
Bubble plot
Stem and Leaf plot
4
Q

When would you use a pie chart?

A

If you want to show pieces of a whole e.g. demographic breakdown.

5
Q

When would you use a bar chart?

A

When comparing categorical (x) and numerical (y) data.

6
Q

When would you use a Histogram?

A

When comparing continuous quantitative (x) and quantitative counted (y) (e.g. heart rate vs frequency)

7
Q

When would you use a dot-plot?

A

Similar to bar charts but with smaller data sets. More visually appealing.

8
Q

When would you use a box and whiskers chart?

A

To summarise a single data set (more for non parametric numerical data)

9
Q

What do box and whiskers charts show?

A

There are 5 numbers (Lower extreme, lower quartile, median, upper quartile, upper extreme). The box shows the interquartile range and the whiskers show the extremities.

10
Q

When would you use a scatter plot?

A

To show similarities between two data sets. It is conventionally used between two continuous numerical variables. A line can be added to show correlation.

11
Q

What are line graphs and cumulative frequency curves?

A

Line graph- LIne joining points, time and dependent variable

Cumulative frequency graph- Similar to histogram but uses curve (incl. dose-response)

12
Q

What are bubble plots and stem and leaf plots?

A

Bubble- similar to scatter but size of bubble represents a third variable
Stem and leaf- Displays general distribution, hybrid between table and graph. Used for moderately sized data sets.
