Final answer:
The statement that measures of shape, centre, and spread do not work on bar graphs is false. While bar graphs display categorical data and are not typically used for statistical measures, the mode, which is a central tendency measure, can be visually inferred from the heights of the bars.
Step-by-step explanation:
The statement 'Measures of shape, centre, and spread do not work on bar graphs.' is False. Measures of shape, centre, and spread are statistical tools used to describe the characteristics of data. While bar graphs are typically used to show categorical data, and therefore do not often lend themselves to measures of centre or spread, the concept of shape can still be observed. For example, the relative heights of the bars can give a visual indication of the mode, which is a measure of central tendency.
The shape of a bar graph may not directly tell you about its statistical distribution like a histogram does for quantitative data, but you can still interpret certain aspects. Remember that true statistical measures of shape, such as skewness and kurtosis, are more commonly applicable to histograms and frequency distributions than to bar graphs.
