Statistics
In two context statistics can be difined. One is in singular sense of statistics and another is the plural sense of statistics. Both of the two cotext and aspects of statistics is important in different mathematical analysis.
Statistics as plural sense
In a plural sense of statistics is describing something in a neumerical value. Just think about you are trying to making a segmentation of a population of a certain area on the basis of gender. The first step of the statistical analysis of your work will be measuring a numerical value of the number of male and female people in this area.
Singular sense
Statistical method is important in order to do an effective statistical process. If the numerical statistical data is very large then it is important to introduce an effective way and a systematic method to collect, organise, present, analyse and interpretation of the statistical data.
Phase of statistical investigation
The phases of statistical investigation is nothing but a stepwise progression of any statistical investigation. In generally, anyu statistical investigation is based on five phase, these are
Collection of data
Organising of data
Presentation of data
Analysis of data
Interpretation of data
Let us discuss about the phases of the statistical investigation
To make a wise dicision about some phenomenon there need sonme sorts of information related with the phemenon. Hence, information collection is required. The collected information will be bulk in size and may not have without error. Collected data may be related with phemenon or may not related with the phemenon. Even, relative data and information may be anomalous characteristiocs.
Organising of data
Just think about the term organisation. The term organisation means a systematic and effective stage of doing something effectively. In more simply to say organising is making groups. For examples, your friend gave you number of 10 sticks, 3 with red color, 5 with white color and two with green color. You seperates the sticks in three parts with colour. That means you have done an organisation..
Presentation
Any organised form of data should be present for analysis.
Analysis
Analysis of any statistical method is done in order to investigate the effectiveness of the infoirmation as well as investigate the probable error in the process.
Interpretation
Interpretation of any statistical method is the last step to do the conclusion of the statistical investigation.
