Answer: It looks like you need a short answer, if that's really the case here: Smaller intervals in a histogram give more information and show details in the data better. Larger intervals make it harder to see important information in the data.
if you want an long answer here: One advantage of using smaller intervals in a histogram, as opposed to larger intervals, is that it provides a more detailed and accurate representation of the data. Smaller intervals allow for a better distribution of the data points and a finer resolution of the frequency of different values, making it easier to see patterns, outliers, and trends in the data. Additionally, smaller intervals can help to identify specific values or ranges of values that may be particularly important or interesting. On the other hand, larger intervals can obscure important details in the data and make it harder to identify specific patterns or trends.
