I have input my data into the spreadsheet but the histogram seems to have an error. Each value is contained the the bar to the right of the number value but it seems like 63 and 64 have combined into one bar on the histogram. How do I fix this? 63 should only go up to 5 and 64 should only go up 3. The histogram has combined them to be 8 and I'm wondering how to fix this.
