Question
Fill in the gaps:
By joining the centre of each column in the histogram we create a __________ __________.
Solution
By joining the centre of each column in the histogram we create a frequency polygon.
A frequency polygon is a graphical representation used in statistics that connects the midpoints of each bar (column) of a histogram with straight lines. This method provides a clear view of the distribution of the data, allowing for easier identification of trends and patterns when comparing multiple data sets. It is particularly useful because it emphasizes the shape of the data distribution, which can be essential in inferential statistics. The frequency polygon can also be compared to other distributions by overlaying additional polygons, making it a versatile tool for data analysis.
