    CanonNikonFujifilmCanonNikon
    NikonCanonCanonCanonCanon
    OlympusCanonCanonCanonNikon

    NikonCanonNikonCanonSony

For the given data, a frequency of various brands of cameras bought is found out. This is simply the number of times a particular camera brand is bought for example; Olympus is bought for 2 times. This indicates number of times Olympus occurs in the data set. A relative frequency is number of times a particular brand is bought divided by number of data points. For Olympus it is 2/45 = 4.44%. So we list out various brands and their relative frequency in an excel sheet as below.

    Brand of cameraFrequencyRelative frequency
    Canon23(23/45)51.11%
    Fujifilm3(3/45)6.67%
    Nikon11(11/45)24.44%
    Olympus24.44%
    Sony613.33%
    Total45100.00%

A frequency bar diagram is drawn by selecting the column 1 and 3 of above table.
