The approximate value of the median may be obtained graphically from the ogive. It also keeps us updated with the total frequency of everything. Log in. We can find the median value if both the less than and larger than cumulative frequency curves are displayed on the same graph. But to interpret the rate of change you need to look past steep lines to decipher subtler changes by time period. The following are advantages of a bar graph: Show each data category in a frequency distribution. The advantages of grouping data are, it improves the accuracy/ efficiency of estimation, helps to focus on the important subpopulations, and ignores irrelevant ones. The disadvantage is that you are lumping scores together, thus losing some of the information in the original scores.
