Sets and Numbering Systems
Mathematical research begins with the study of sets and the development of number systems. The whole mathematical system can be represented as a “set”; therefore, it is important for us to understand the meanings, notes, and structures of the “sets”.
Matrices and Determinants
Definition: A matrix is a rectangular arrangement of numbers in rows and columns. Matrix layout number of rows and columns. Included are numbers in the matrix.

Statistics
Methods of collecting, organising and analysing numerical information are called statistics. The parts of numerical and non-numerical information are called data. In order to collect data, you need to look at or measure a particular asset; this structure is called a variable.
Quality Variable
A variable is a symbol if it is not likely to take a numerical value. The variable is the volume if it can take a numerical value. A quantity variable that can take any value in a given range is called a continuous variable. A volume variable with clear steps between its possible values is called a discrete variable.
Descriptive Statistics
Descriptive statistics include those methods related to collecting and interpreting data collection in order to produce meaningful information.
Inferential Statistics
Inferential Statistics covers those methods related to the analysis of a small data set that leads to speculation or speculation about the entire data set.
Frequency distribution
Distribution frequency is a statistical table presentation that helps to analyse large data sets. Distribution frequency summaries statistical data by assigning it to specific groups, or intervals.
Relative Frequency
The related frequency is calculated by dividing the frequency of each episode by the total number of observations. Simply put, the related frequency is the percentage of total view that falls within each interval.
Cumulative Frequency
Cumulative Frequency is calculated by summarising the frequencies starting at the lowest point and continuing at the top. The accumulated frequency of any given interval is the sum of the frequent frequency and includes the given interval.
