Histogram refers to the visual presentation used for summarizing the discrete or the continuous data and the example of which includes the visual presentation on the graph , the complaints of the customer made in the bank on the different parameters where the most reported reason of the complaint will have the highest height in the graph presented. Histograms. Download the corresponding Excel template file for this example. A population is the object upon which we collect data. The histogram is represented by a set of rectangles, adjacent to each other, where each bar represent a kind of data. Each bar (class or column) is the same width . D) The bars are drawn adjacent to each other because the data is continuous. A histogram is used to summarize discrete or continuous data. Usually, there is no space between adjacent columns. For instance, while the mean and standard deviation can numerically summarize your data, histograms bring your sample data to life. When taking a sample from the population, the variable involved will always be qualitative. A histogram is made of a series of intervals, called classes. Each bar typically covers a range of numeric values called a bin or class; a bar's height indicates the frequency of data points with a value within the corresponding bin. 2.
