**Frequency Polygon Worksheet Printable Maths Worksheets**

A frequency polygon is a graphical form of representation of data. It is used to depict the shape of the data and to depict trends. It is usually drawn with the help of a histogram but can be drawn without it as well. A histogram is a series of rectangular bars with no space between them and is used to represent frequency distributions.... Calculating the median from a frequency distribution Objective: On completion of the lesson the student will be able to determine the median from a cumulative frequency polygon. 11

**Lesson 2.5 Data Analysis Descriptive Statistics**

A frequency polygon is a graphical form of representation of data. It is used to depict the shape of the data and to depict trends. It is usually drawn with the help of a histogram but can be drawn without it as well. A histogram is a series of rectangular bars with no space between them and is used to represent frequency distributions.... Frequency Polygon frequency polygon: graph that uses lines that connect points plotted for the frequencies at the midpoints of the classes; frequencies are represented by the heights of the points To construct a frequency polygon: Find the midpoints of each class Draw the x and y axes. Label the x-axis with the midpoint of each class then use a suitable scale for the frequencies on the y-axis

**Frequency Polygon Worksheet Printable Maths Worksheets**

Frequency polygons can be used to analyze data sets in many different ways. They are also a great way to visualize and compare two sets of data.... In order to find the median value we look at the total number of values we have. In this case there were 50 matches played. We add one to this then we then half this, to get 25.5 and from the cumulative frequency axis (the vertical axis) we draw a line across to the steps and then down. If the number of items is large enough we can simply use Â½n rather than Â½(n+1).

**Solutions to Mode Median Mean and Variance Problems**

Data from a frequency distribution can be used to make graphs including the histogram and the frequency polygon. The table below lists the class intervals and â€¦... 27 (use the mid point on a frequency polygon) 40 (use the last point on the cumulative frequency graph) Which point would you plot on a cumulative frequency graph for the interval 0 < t â‰¤ 40
