![]() A right-skewed distribution usually occurs when the data has a range boundary on the left-hand side of the histogram. In a right-skewed distribution, a large number of data values occur on the left side with a fewer number of data values on the right side. In a bimodal distribution, the data should be separated and analyzed as separate normal distributions.Ī right-skewed distribution: A right-skewed distribution is also called a positively skewed distribution. Distributions of a HistogramĪ normal distribution: In a normal distribution, points on one side of the average are as likely to occur as on the other side of the average.Ī bimodal distribution: In a bimodal distribution, there are two peaks. In addition, it can show any outliers or gaps in the data. The median and distribution of the data can be determined by a histogram. Histograms can display a large amount of data and the frequency of the data values. For a histogram with equal bins, the width should be the same across all bars.Ĭreating a histogram provides a visual representation of data distribution. The bars: The height of the bar shows the number of times that the values occurred within the interval, while the width of the bar shows the interval that is covered.Y-axis: The Y-axis shows the number of times that the values occurred within the intervals set by the X-axis. ![]() X-axis: The X-axis are intervals that show the scale of values which the measurements fall under.The title: The title describes the information included in the histogram. ![]() ![]() However, a histogram, unlike a vertical bar graph, shows no gaps between the bars. In other words, it provides a visual interpretation of numerical data by showing the number of data points that fall within a specified range of values (called “bins”). A histogram is used to summarize discrete or continuous data. ![]()
