Question

1. define and draw a histogram.

Explanation:

A histogram is a graphical representation of data where the data is grouped into intervals (bins) and the frequency of data - points falling into each bin is represented by the height of a bar. The bars are adjacent to each other. To draw a histogram: first, determine the data range and divide it into appropriate bins. Then, count the number of data - points in each bin. Finally, plot the bins on the x - axis and the frequencies on the y - axis, and draw bars with heights corresponding to the frequencies.

Answer:

A histogram is a bar - chart like graph used to represent the distribution of a dataset. It consists of contiguous (adjoining) bars. For drawing, steps include binning data, counting frequencies per bin, and plotting with bins on x - axis and frequencies on y - axis.
