Univariate, bivariate and multivariate are the various types of data that are based on the number of variables. Variables mean the number of objects that are under consideration as a sample in an experiment. Usually there are three types of …

It is the numeric value that separates the higher digit values from the lower digit values. It is represented by . The median has some limitations. Median can only be defined for dimensional data and it is not dependent on …

The average value of a sample or population data is known as the arithmetic mean of that data. The sample mean is the sum of all the values divided by the number of values a sample contains. When the data …

Mean, median and mode are the various methods that give an overview of the statistical data numerically. A given statistical data can be represented either graphically or numerically. Graphical description of data is with the help of a bar graph, …

Discrete variable is a type of quantitative variable that only take a finite number of numerical values from the defined limits of the variable. It neglects all those values that are in decimal. Discrete variable is also known as categorical …

It is a characteristic that is either given in the form of value or quantity and that varies over the time is known as variable. Values are the mathematical numbers (i.e. 0,1,2,3,4,5,6,7,8 and 9) and these numbers may be 1-digit …

For easy understanding the variations in data. After the collection and tabulation of data, it can be represented by a graph. Most common graphs are Bar graphs Pie graphs Line graphs Bar Graph Bar graph represents the relation between class interval/group …

When a large list of numerical data is given, then to reduce the numerical work a frequency table is constructed that arranges the same data in the same class or group and that class will be distinct to the data …

Inferential statistics is a study of various procedures that are applied to conclude from the characteristics of a large group of data and that large group of data is known as population. Inferential statistics deliver answers about population related questions …

Descriptive statistics is the branch of statistics that deals with the quantitative description of the basic features of data collection. Descriptive statistics aim is to rearrange the data in a sequence and at the end summarize the data and represent …
