Hello students, here in this video we are going to study a very important topic as, Statistic and cumulative frequency curve or ogive of chapter 14 form CBSE class 10 maths.
What is Statistics?
Statistics is simply collecting and summarizing the data. To be precise, statistics is the study of the collection, analysis, interpretation, presentation, and organization of data to make it more presentable and easy to interpret.
Statistics is one of the parts of mathematics in which we study the collecting, organizing, analyzing, interpreting and presenting data.
Statistics are very helpful in real-life situations as it is easy to understand if we represent data in a particular number which represents all numbers.
Ogive Definition and Introduction
The Ogive is defined as the frequency distribution graph of a series. The Ogive is a graph of a cumulative distribution, which explains data values on the horizontal plane axis and either the cumulative relative frequencies, the cumulative frequencies or cumulative percent frequencies on the vertical axis. Create the Ogive by plotting the point corresponding to the cumulative frequency of each class interval.
The graphs of the frequency distribution are frequency graphs that are used to exhibit the characteristics of discrete and continuous data. Such figures are more appealing to the eye than the tabulated data. It helps us to facilitate the comparative study of two or more frequency distributions.
