1. The problem is to understand how to plot a histogram. 2. A histogram is a graphical representation of data distribution, showing the frequency of data points within specified intervals called bins. 3. To plot a histogram, first collect your data set. 4. Decide on the number of bins or intervals to divide the data range. 5. Count how many data points fall into each bin. 6. On the x-axis, place the bins (intervals), and on the y-axis, place the frequency counts. 7. Draw bars for each bin where the height corresponds to the frequency of data points in that bin. 8. Histograms help visualize the shape, spread, and central tendency of the data. 9. Important rules: bins should be contiguous and non-overlapping, and the width of each bar should be consistent. 10. Many software tools like Excel, Python (matplotlib), or R can plot histograms easily by inputting the data and specifying bins.
