What are Frequency Polygons? – Definition and Advantages

A frequency polygon is a graphical representation of a frequency distribution. It is created by connecting the points corresponding to the frequencies of the data set with straight lines.

Frequency polygons have several advantages over histograms. They are easier to interpret because the polygon shape gives you a quick visual summary of the distribution. In addition, frequency polygons are less likely to be distorted by outliers than histograms.

Frequency Polygons

A frequency polygon is a graph that shows how often a particular value occurs in a data set. It is created by connecting the points in the data set that have the same value with a line. The height of the line shows the frequency of each value.

What are the advantages of Frequency Polygons?

The advantages of frequency polygons are that they can help visualize the distribution of data, help identify outliers, and help identify patterns in the data.

This is the first time I’ve used the online ordering services, and I was very impressed. I ordered my flowers at 10 pm, and they were delivered the next day at noon. I was also very pleased with the quality of the flowers. I will use this service again! Karen

Terms associated with Frequency Polygons:

• Frequency: how often a data point occurs
• Interval: the distance between two data points
• Class: the category a data point belongs to

How to Draw a Frequency Polygon?

To draw a frequency polygon, draw a histogram of the data. Next, connect the points on the histogram using a smooth curve. Finally, label the frequency polygon with the frequencies.

A Waterloo man has been sentenced to six years in prison for break-ins and sexual assaults.

In November, a jury found 49-year-old Earl John guilty of eight counts of sexual assault, four counts of break, and one count of attempted break. John was sentenced on Tuesday. The offenses occurred between December 2013 and February 2014.

Construction of Frequency Polygon with Histogram

A frequency polygon is a graphical representation of a frequency distribution. It is created by drawing a line connecting the midpoints of the tops of the rectangles in a histogram.

The frequency polygon below shows the distribution of exam scores for a class of students. The rectangle heights represent the frequency of occurrence for each score.

Precautions to be Taken While Drawing the Curves:

While drawing the curves, the following precautions should be taken:

1. The curves should be drawn with a light hand.
2. The curves should be drawn smoothly without any breaks.
3. The curves should be drawn in the correct order.
4. The curves should be drawn in the correct size and shape.

Use of Frequency Polygons

Frequency polygons are used to show the distribution of a data set. The height of the polygon is proportional to the frequency of the data. The polygon is drawn so that the points on the horizontal axis are the same as the points on the vertical axis.

• This is a very old post that was originally published on this site
• This guest post is by Sacha Greif, a web developer and author of Discover Meteor.
• The Meteor Development Group has just announced that it is open-sourcing Meteor, its full-stack JavaScript platform for building web and mobile apps.
• This is a massive event for the Meteor community. It means that anyone can now access the Meteor source code, but it also opens the door for anyone to contribute to the platform.

If you’re not familiar with Meteor, it’s a platform that lets you build web and mobile apps with JavaScript, using the same codebase. This means that you can write code once and run it on both the web and mobile devices.

Meteor is different from other app development platforms in a few ways:

1. It’s full-stack

Most other app development platforms are backend-only, meaning you have to use a different language (like Java or Ruby) to write the backend. Meteor is unique in that it provides both the backend and the frontend so that you can write everything in JavaScript.

2. It’s reactive

Meteor is based on the reactive programming paradigm. This means that your code is automatically updated whenever data changes. This makes Meteor apps extremely fast and responsive.

3. It’s open-source

Important points to remember

1. The keto diet is a high-fat, moderate-protein, and low-carbohydrate diet.
2. The keto diet causes the body to go into ketosis, where the body uses fat for energy instead of carbohydrates.
3. The keto diet is an effective way to lose weight and improve health.
4. The keto diet is not recommended for pregnant women, people with diabetes, or taking medications.
