Question

Burt has a job selling suits at a local department store. Since he must sell a certain number of suits each month, he needs to know how many suits he sells as the month progresses. Below is the histogram he designed.

Explain, using complete sentences, whether or not this is the most appropriate format for representing this data and why. If it is not the best format, explain which format should have been used instead

Answer 1

Everything about the histogram burt designed is good. Theres nothing wrong with it ; he stated everything that is qualified the weeks, the number of suits and he wrote each number on each week on exactly how much he sold.

Answer 2

The use of a histogram to present the data is appropriate, as the data to be presented is a continuous set of data. Continuous in the sense that it has data every day of the week for one month.

Step-by-step explanation:

HISTOGRAM

Histogram is a specific type of bar chart, where the categories are ranges of numbers. It is a plot that enables you to determine, and display, the underlying frequency distribution (shape) of a set of continuous data. This permits the inspection of the data for its underlying distribution (e.g., normal distribution)

To construct a histogram from a continuous variable (in this case number of suit sold per month) you first need to split the data into intervals, called bins. In the question above, Time (in weeks) has been split into bins, with each bin representing 1 week. Each bin contains the number of No of suit sold (occurrences) of scores in the data set that are contained within that bin. For the above data set, the frequencies in each bin have been tabulated along with the scores that contributed to the frequency in each bin. Unlike a bar chart, there are no "gaps" between the bars. This is because a histogram represents a continuous data set, and as such, there are no gaps in the data (although you will have to decide whether you round up or round down scores on the boundaries of bins).

When choosing the bin width, there is no right or wrong way, but there are rules of thumb. Just ensure that the bins are not too small or too large

In a histogram, the area of the bar usually indicates the frequency of occurrences for each bin. That is, the height of the bar does not necessarily show how many occurrences of scores there were within the individual bin. Rather, it is the product of height multiplied by the width of the bin that indicates the frequency of occurrences within that bin. The height of the bars is often incorrectly assessed as indicating frequency rather than the area of the bar is because most histograms often have equally spaced bars (bins), and under these circumstances, the height of the bin does reflect the frequency.
