If you would like a column of evenly-spaced values, such as for frequency bins, Excel can fill them in for you. Put the first two values in and highlight those two cells. Click on the lower right-hand corner and drag downward; Excel will continue the pattern you began.
Graphical display of the frequency table can also be achieved through a frequency polygon. To create a. the intervals are labeled on the X-axis and the Y axis represents the height of a point in the middle of the interval. The points are then joined are connected to the X-axis and thus a polygon is formed.So, frequency polygon is a graph that is obtained by connecting the middle points of the intervals. We can create a frequency polygon from a histogram also.If the middle top points of the bars of the histogram are joined, a frequency polygon is formed. Frequency polygon and histogram fulfills the same purpose.o create a. the intervals are labeled on the X-axis and the Y axis represents the height of a point in the middle of the interval. The points are then joined are connected to the X-axis and thus a polygon is formed. So, frequency polygon is a graph that is obtained by connecting the middle points of the intervals.
