SSC CGL Tier 2 - Statistics Syllabus & Pattern

As all of you are aware, In SSC CGL Tier 2 there are Paper 3 & 4 which are optional paper . In  this article i have discussed the Syllabus and Pattern for Paper 3 i.e. Statistics Paper. This paper is conducted for Junior Statistical Officer (JSO). Aspirants who have applied for JSO have to take Quantitative Aptitude (Paper I), English Comprehension (Paper II) and Statistics (Paper III).

SSC Jr. Statistical Investigator Exam Pattern

The 3rd paper of SSC CGL Tier 2 is of Jr. Statistical Investigator.  Below I have discussed exact pattern of paper is:

Section	Number of Questions	Maximum Marks	Time	Mode of Exam
Statistics	100	200	2 Hours	Online

*There will be negative marking of 0.5 marks for every wrong response.

The above-listed topics are the complete set which you are required to cover. While preparing for this paper keep some points in mind:-

• Cover syllabus from a good book. While deciding book, the language of the book and the quality of content is an important factor to be kept in mind.
• Don't go in-depth of any topic. Cover the basic definition and characteristics.
• Don't skip numerical questions in Statistics. There are certain topics in Statics which are of high weight-age in terms of concepts and numerical questions i.e. Conditional probability, Bayes’ theorem, Different types of moments and their relationship, Determinations of trend component by different methods etc.
• Stick to the above -given syllabus while preparing for this paper.
• After covering above-listed topics start taking mock tests. And also do the proper analysis of the mock tests for proper understanding of the grey areas to cover.
• Try to manage time for this paper also along with the preparation of other papers of Tier-2.
• Don’t waste much time on a single topic. As time resource is scarce, you have to use it very intelligently.
• Do a proper analysis of quizzes and mock tests you take.

The aspirants are advised to go through this article very attentively as each and every minute details have been covered which are essential for the paper of Jr. Statistical Investigator paper.
