1.1What type(s) of data are best for using the following?
1.1.1 A stem-and-leaf plot (2)
A stem-and-leaf plot is typically used to display numerical data, specifically
discrete data. It can be used for both small and large data sets.
1.1.2 A bar chart (2)
A bar chart is best used for visualizing categorical or discrete data. It is
suitable for comparing different categories or groups, such as comparing
sales by product category or comparing the population of different countries.
1.1.3 Pie chart (2)
Pie charts are best for displaying categorical data, specifically when
comparing the parts of a whole or the proportions of different categories.
This type of chart is visually effective for representing data that can be
divided into distinct categories and where the relationship between those
categories is important to understand.
1.1.4 Scatter plot (2)
- Continuous numerical data: Scatter plots are commonly used to visualize
the relationship between two continuous numerical variables, such as
plotting the age of individuals against their blood pressure readings.
- Discrete numerical data: Scatter plots can also be used to show the
relationship between two discrete numerical variables, such as plotting the
number of hours studied against the corresponding test scores.
1.1.5 Line graph (2)
- Time series data: Line graphs are typically used to display data that changes
over time, such as the daily temperature over a month or the stock prices
over a year.
- Continuous numerical data: Line graphs can also be used to show the
relationship between two continuous numerical variables, such as plotting
the population size of different cities against their average income.
