Suppose you are visualizing survey data where the responses are highly skewed towards one particular option. How can you accurately depict this bias in your visualization?
- Use a pie chart with equal slices for each response
- Use a bar graph with the y-axis starting at the lowest response value
- Use a bar graph with the y-axis starting at zero
- Present the data in a table, because graphs can't show this
If the responses to a survey question are highly skewed towards one option, a bar graph with the y-axis starting at zero can accurately depict this bias. This type of graph clearly shows the difference in the number of responses for each option, allowing viewers to see the skewness.
