The histogram is a pictorial representation of a dataset distribution with which we could easily analyze which factor has a higher amount of data and the least data. In other words, the histogram allows doing cumulative frequency plots in the x-axis and y-axis.
Actually, histograms take both grouped and ungrouped data. For a grouped data histogram are constructed by considering class boundaries, whereas ungrouped data it is necessary to form the grouped frequency distribution. They help to analyze the range and location of the data effectively. Some common structure of histograms is applied like normal, skewed, cliff during data distribution. Histogram Takes continuous variable and splits into intervals it is necessary to choose the correct bin width.
The major difference between the bar chart and histogram is the former uses nominal data sets to plot while histogram plots the continuous data sets.
R uses hist function to create histograms. This hist function uses a vector of values to plot the histogram. Histogram comprises of an x-axis range of continuous values, y-axis plots frequent values of data in the x-axis with bars of variations of heights.
For analysis, the purpose histogram requires some built-in dataset to import in R. R and its libraries have a variety of graphical packages and functions. Here we use swiss and Air Passengers data set. The following example computes a histogram of the data value in the column Examination of the dataset named Swiss.
Hist is created for a dataset swiss with a column examination. Tips: Use the Chart Design and Format tabs to customize the look of your chart. Tap to select your data. If necessary, you can customize the elements of the chart.
