If you are a beginner, knowing how to draw them together is essential.Ĭonsider the following example for explanatory purposes: Worked Example – Men and Sports:Ī survey was conducted amongst 50 men aged 16 to 74 years. In this section, we will show you how to combine a histogram and a curved line in a chart. How to Draw a Histogram and a Curved Line Chart Together Difficult to draw and interpret for data above 50 values.The intermediate values between two points may be misleading.However, curved line graphs have some limitations, which are mentioned as follows: You want to make a prediction of future values in the data set.You want to highlight changes in one variable for constant values of the second variable.A curved line graph is a convenient statistical representation when: The curve bends upwards or downwards to show a trend in the data set. It basically denotes the change that has taken place over time in a given set of data. When you need to find out the amount of input in the data set (For example: how many people the survey was conducted on)Ī curved line graph is another way to display the given numerical information on a chart.When multiple categories are present in the data.Histograms are inconvenient in the following scenarios: They work well with a large range of data.Histograms are quite popular and widely used because: It can also be described as a frequency distribution that shows how often a certain value occurs in a given set of data. What is a Histogram?Ī histogram is a graphical representation of a set of data that displays data values in a specified range. However, both the histogram and line graphs have different properties and characteristics that must be understood.
The data must be discrete and continuous. In statistics, a histogram and a curved line graph are both ways to display a given set of numerical data on a chart.
