### How to Prepare for Statistics?

Candidates must prepare for statistics subject in GATE 2021 strategically. The subject is more inclined towards mathematics and numericals. You should practice a lot for this particular subject. You should complete the syllabus on time with a sufficient amount of practice. Then move on to solving questions papers of past years and mock tests. Also, practice from online test series. Your preparation should be thorough. We have put together a few tips that will help you prepare better for the GATE 2021. You can check them out below.

**Start easy**

It is always better to start your preparation from the easy topics. It will give you the confidence to move forward in your preparation. This way you can cross those topics from the syllabus and you will be left with the difficult topics only. These topics require more attention and hard work. Separate them in medium and hard difficulty levels. Complete the medium topics before hard ones. This way you will cover most of the syllabus and including the important topics.

**Focus on practicing**

Statistics is all about quantitative aptitude. You focus should be on solving more and more numericals. Try to practice numericals of all difficulty level. This will help you big time in the exam. Don’t shy away from hard topics or problems that are difficult to solve. Also, practice quick mental calculations. This will save a lot of your time in the exam. Your mind will be alert and sharp and it will not be difficult to solve questions in a matter of minutes.

**Complete the syllabus**

Completing the syllabus is very important. Even if you start your preparation right at the moment, you will still have enough time to cover the entire syllabus in a few months and still have a month for just revision. The subject is not foreign to many students as they have already studied it in school. Make use of that prior knowledge. Try to cover it all in about 4-5 months. It is enough to complete the syllabus if you prepare smartly.

**Practice Mock tests **

Mock tests are an important part of your preparation. You should take weekly and subject-wise mock tests. If possible take monthly mock tests as well. These regular mock tests will help you in keeping your preparation in check. After every test analyze your performance. Identify your weak areas and work on them accordingly. Analysis is an important step. Without it, your mock test practice is of no use. So make sure that you analyze each one of them properly.

**Solve Previous years question papers**

Along with mock tests, you should also solve previous year question papers. Pick up the last 5-6 years question papers and start solving them. Observe the trend of questions that have been followed over the past years. Practice time management while solving papers. Prepare a strategy of how to attend the paper and in what sequence.

**Do revision**

Revision should be done after every topic is completed. Make it a habit so that you don’t slack while revising. You can also prepare running notes. They will come in handy in the last month when you will be revising. Revising from notes will also be easier. In case you don’t remember some topics even after reading your notes then you can refer to the study material.

### GATE Statistics Books for Preparation

Prepare for your GATE 2021 from the best study material only. Your study material should be of good quality. Pick books from renowned publications and authors. The quality of your study material reflects the quality of your GATE preparation. Especially if you are doing self-preparation, then you must invest in good quality books and notes. If you are still having trouble finding the right study material, then you can refer to the list of books we have given below.

Title of the book | Name of the Author/ Publication | Link to buy |

Programmed Statistics (Question-Answers) | B.L. Agarwal | LINK |

Miller and Freund’s Probability and Statistics For Engineers | Pearson | LINK |

### What is Statistics?

Statistics is one of the mathematics branches that includes working with data collection, organization, analysis, interpretation and presentation. In Engineering Statistics is mixed with engineering through scientific methods for analyzing data. It involves data related to manufacturing processes including component dimensions, tolerances, types of materials, and fabrication process control. For engineering analysis, various methods are used that are displayed as histograms to visualize the data.

### GATE 2021 Preparation FAQs

**Q1. Which books should I prepare for Statistics?****Ans.** You can prepare from the books we have suggested in this article.

**Q2. Can I leave some topics in the syllabus? ****Ans.** You should prepare the whole syllabus. If you don’t have enough time then you can do the important topics and solve mock tests.

**Q3. How many months are needed to complete the syllabus?****Ans. **Ideally your syllabus should be completed in about 4-5 months. The last/6th month should be for revision.
