Reference Notes of Management
Statistics is the art of collecting, analyzing, presenting and interpreting data.
Statistics is sub-divided into two categories:
- Descriptive Statistics
- Inferential Statistics
Descriptive Statistics gives description or we can say it focuses on collection, presentation and characterization about a sample. Inferential Statistics helps to predict and estimate the possible characteristics of the population from the sample data drawn from the population.
|S.n||Descriptive Statistics||Inferential Statistics|
|1.||Descriptive Statistics gives description or we can say it focuses on collection, presentation and characterization about a sample.||Inferential Statistics helps to predict and estimate the possible characteristics of the population from the sample data drawn from the population.|
|2.||Descriptive Statistics only describes some certain characteristics of the data.||Inferential Statistics deeply analyzes the statistical data and observations.|
|3.||Descriptive Statistics helps in dealing with the central tendency and spread of the frequency distribution.||Inferential Statistics helps in studying details about the hypothesis test and confidence level.|
|4.||Descriptive Statistics can be measured either numerically (mean, median, mode) or graphically.||Inferential Statistics cannot be always measured in exact numbers.|
|5.||Descriptive Statistics helps to produce error free results as it deals with the small population.||Inferential Statistics may not produce error free results as it takes whole population for drawing conclusion.|
|6.||Drawing conclusion in descriptive statistics is limited within the given data i.e. we cannot make conclusions beyond the given data.||Drawing conclusion in Inferential statistics is unlimited i.e. the educated predictions and guesses can be made on the basis of the parameters of the given population.|
