# What is the difference between a polygon and an ogive?

The most important difference between them is that an ogive is a plot of cumulative values, whereas a frequency polygon is a plot of the values themselves. So, to get from a frequency polygon to an ogive, we would add up the counts as we move from left to right in the graph.

### How do you make a frequency polygon?

To create a frequency polygon, follow these steps:
1. Create a histogram.
2. Find the midpoints for each bar on the histogram.
3. Place a point on the origin and at the end of the histogram.
4. Connect the points.
• #### What is a frequency diagram?

Frequency diagrams and polygons. This frequency diagram shows the heights of 200 people: You can construct a frequency polygon by joining the midpoints of the tops of the bars. Frequency polygons are particularly useful for comparing different sets of data on the same diagram.
• #### What is an ogive in statistics?

An ogive (oh-jive), sometimes called a cumulative frequency polygon, is a type of frequency polygon that shows cumulative frequencies. In other words, the cumulative percents are added on the graph from left to right. An ogive graph plots cumulative frequency on the y-axis and class boundaries along the x-axis.
• #### What is the modal class interval?

This is answered by examining the meaning of each term in the phrase: modal means the one that occurs most often (averages: mode), a class interval is the width of one of your groups in the frequency table or, the class interval is what you use when grouping data together, e.g., if you counted the number of pencils in

### What is meant by frequency polygon?

Frequency polygons are a graphical device for understanding the shapes of distributions. They serve the same purpose as histograms, but are especially helpful for comparing sets of data. Frequency polygons are also a good choice for displaying cumulative frequency distributions.
• #### What is the difference between frequency polygon and histogram?

Frequency histogram and polygon. 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.
• #### What is the difference between a frequency polygon and a line graph?

A frequency polygon is a line graph. The points are often not connected with a smooth line, but with straight line segments. Frequency polygons are used to show the changes over time.
• #### What is ogive for?

An ogive (oh-jive), sometimes called a cumulative frequency polygon, is a type of frequency polygon that shows cumulative frequencies. In other words, the cumulative percents are added on the graph from left to right. An ogive graph plots cumulative frequency on the y-axis and class boundaries along the x-axis.

• #### What is Data Visualization in big data?

Data visualization is a general term that describes any effort to help people understand the significance of data by placing it in a visual context. Patterns, trends and correlations that might go undetected in text-based data can be exposed and recognized easier with data visualization software.
• #### What is a data presentation?

Data can be presented in various forms depending on the type of data collected. A frequency distribution is a table showing how often each value (or set of values) of the variable in question occurs in a data set. A frequency table is used to summarize categorical or numerical data.
• #### What is graphic presentation of data?

A chart can represent tabular numeric data, functions or some kinds of qualitative structure and provides different info. The term "chart" as a graphical representation of data has multiple meanings: A data chart is a type of diagram or graph, that organizes and represents a set of numerical or qualitative data.
