data={97,90,91,98,93,100,90,98,91,93,98,93,97,93,80,95,93,99,96,80,98,
85,94,98,96,88,93,92,88,97};

Needs["Graphics`Graphics`"];

Histogram[data];

It is not clear how you want to handle values on the interval boundaries.

Histogram[data, 
    HistogramCategories->Table[k,{k,80,100,4}],
    Ticks->IntervalCenters];

Histogram[data, 
    HistogramCategories->Table[k,{k,80,101,4+10^-6}],
    Ticks->IntervalCenters];
