# NOTE:

If you attend classes regularly and understand what is taught in class then you will not require additional videos for this subject. You will just require some practice.

The notes given for each module covers all types of questions. Also if you miss anything or you don't understand properly what faculty is teaching obviously you have the saviors- Gajendra Purohit and Dr Puspendra's Playlists. Since everything in it is not in order of our syllabus., we have arranged it for you.

The recommended books for this course can be downloaded from here

Apart from that, we have uploaded material by SIAM. It includes both videos and notes for all modules

**Videos to watch:**
If you find skewness and kurtosis a bit difficult you can watch the below videos.
Skewness and kurtosis-1
Skewness and kurtosis-2

**SIAM's Videos**
Mean, Median, Mode and Empirical Relations, Range and Mean Deviation, Standard Deviation, Quartile Deviation

**Notes:**
Just go through this pdf and SIAM's notes and you are good to go.

**Topics Included:** *Introduction -random variables-Probability mass Function, distribution and density functions - joint Probability distribution and joint density functions- Marginal, conditional distribution and density functions- Mathematical expectation, and its properties Covariance , moment generating function – characteristic function.*

**Videos to watch:** Follow these videos from Gajendra Purohit's playlist 1 to 4 and 19,20

**SIAM's Videos:**
Probability mass and Density function,
Cumulative Distribution Function,
Joint Probability, Marginal and Conditional Distribution,
Expectation of Random variable and Co-variance,
Problems

Just seeing videos of this module won't help but this will help you understand the concept and get started. After watching this videos if you look at the given notes and do all the questions given you will be completely prepared as all types of questions gets covered.
**Notes** can be sourced from here

**Topics Included:** *Correlation and Regression – Rank Correlation- Partial and Multiple correlation Multiple regression.*

**Videos to watch:** According to the Gajendra Purohit's playlist 21 to 26

**SIAM's Videos**

Again here along with videos you need to practice from notes.
**Notes** can be sourced from here

**Topics Included:** *Binomial and Poisson distributions – Normal distribution – Gamma distribution – Exponential distribution – Weibull distribution.*

**Videos to Watch:** According to the Gajendra Purohit's playlist 5 to 15

After watching videos always do some practice from notes
**Notes** can be sourced from here

**Topics Included:** *Testing of hypothesis – Introduction-Types of errors, critical region, procedure of testing hypothesis-Large sample tests- Z test for Single Proportion, Difference of Proportion, mean and difference of means.*

From this module you have to follow different playlist by Dr. Puspendra
**Videos to Watch:** According to the Dr. Puspendra's playlist 1 to 4

**SIAM's Videos**
Introduction to Sample Techniques,
Single Proportion Test,
Difference of Proportions Test,
Single Mean Test,
Difference of Means Test

Do all types of questions from ppts of your faculty as many times faculties will ask similar type of questions from what they teach. If you want you can refer ppts/notes of Ramesh Kumar D. They will cover all the concepts

**Topics Included:** *Small sample tests- Student’s t-test, F-test- chi-square test- goodness of fit - independence of attributes- Design of Experiments - Analysis of variance – one and two way classifications - CRD-RBD- LSD.*

**Videos to Watch: According to the Dr. Puspendra's playlist 5 to 27**

**SIAM's Videos**
Student's t-Test,F Distribution,Chi Square Test,Design of Experiments and ANOVA

Do all types of questions from ppts of your faculty as many times faculties will ask similar type of questions from what they teach. If you want you can refer ppts/notes of Ramesh Kumar D . They will cover all the concepts

**Topics Included:** *Basic concepts- Hazard function-Reliabilities of series and parallel systems- System Reliability - Maintainability-Preventive and repair maintenance- Availability.*

**Videos to Watch: Reliability and MTTR and MTTF**

**SIAM's Videos: Basic Concepts and Hazard Function,Problems on Hazard Function,System Reliability and Maintainability and Availability**

Go for the formulas and questions in your faculties ppts. If you want you can refer ppts/notes of Ramesh Kumar D. They will cover all the concepts.
