Wikipedia difference between histogram and frequency polygon

Answer 1

Answer:

The frequency histogram is like a column graph without the spaces between columns. The frequency polygon is a special line graph used in statistics. These graphs can be drawn separately or combined. The information in a frequency distribution table can be used to draw these graphs.

*A histogram is a plot that lets you discover, and show, the underlying frequency distribution (shape) of a set of continuous data. This allows the inspection of the data for its underlying distribution (e.g., normal distribution), outliers, skewness, etc.

A histogram is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size. ... Some histograms are presented with the independent variable along the vertical axis and the dependent variable along the horizontal axis.

*A frequency polygon is a graph constructed by using lines to join the midpoints of each interval, or bin. The heights of the points represent the frequencies. A frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table

Answer 2

histogram and frequency polygon

Explanation:

A histogram is built of bins with a width representing the interval, and a height representing the quantity of data points in each interval,

whereas

A frequency polygon is constructed by drawing a point to represent the frequency of a particular interval and connecting that point to the one representing the frequency

points for histogram :

• The scores  go on the  horizontal axis
• Allow a half column width  gap at the  start
• The area of  the column  represents the  frequency for  that score
• The columns  have no space  between  them

points for frequency polygon :

• Polygon starts  at the corner,  one unit  before the  first score
• The points  show the  frequency for  that score
• Polygon  finishes on  the axis, one  number after  the last score
