Question
You are given a dataset of test scores: 55, 60, 65, 70,
75, 80, 85, 90, 95, 100. You want to create a histogram to visualize the distribution of these test scores. Which of the following is not a valid step when creating a histogram in Excel?Solution
Explanation:- A histogram is a graphical representation of the distribution of numerical data. It is used to visualize the frequency of data points falling within certain ranges or bins. To create a histogram in Excel, you need to follow specific steps: 1. Determine the bin ranges: Bins represent intervals of data that you want to group together. For example, you could create bins for 50-60, 60-70, etc., depending on the data distribution and how granular you want the grouping to be. 2. Use the "Insert" tab and select "Histogram" chart: Excel has a built-in histogram chart type that can automatically calculate the frequency of data points within each bin. Simply select the data, go to the "Insert" tab, and choose the "Histogram" chart under the "Charts" group. 3. Specify the number of bins: Excel allows you to specify how many bins you want or let it determine the optimal number of bins based on the data. This choice affects how granular the distribution appears. 4. Ensure that each bin contains at least one data point: While it is generally helpful for each bin to contain data points, this is not strictly required . If there are bins with no data points, they will simply have a height of zero in the histogram.
