How will I know the modal class from a grouped data w/ equal class sizes if the highest frequency is 7 but then it appears thrice in 3 intervals.
34.00  39.69 frequency: 7
39.70 45.39 frequency: 7
62.5068.19 frequency: 7

With your data, the distribution is bimodal, with one mode occurring in the 3445.39 interval and the other in 62.568.19.
