Example 2

easy
Which type of graph would be most appropriate to display the favourite ice-cream flavours of 30 students: a bar graph, a line graph, or a scatter plot? Explain.

Solution

  1. 1
    Step 1: Identify the data type — ice-cream flavour is categorical (not numerical).
  2. 2
    Step 2: A bar graph is used to compare counts across categories. A line graph shows trends over time, and a scatter plot shows relationships between two numerical variables.
  3. 3
    Step 3: Since we have categorical data with frequencies, a bar graph is the best choice.

Answer

A bar graph is most appropriate because the data is categorical.
Choosing the right type of graph depends on the nature of the data. Categorical data is best displayed with bar graphs or pie charts, while numerical data may use histograms, line graphs, or scatter plots.

About Data Representation

Data representation is the process of organizing and displaying data using charts, graphs, or tables so that patterns, trends, and comparisons become easier to see and understand at a glance.
