We work with numbers in arithmetic, while in algebra we use numbers as well as Alphabets such as A, B, C, a, b, and c for any numerical values we choose. We can say that algebra is an extension of arithmetic. For example, the arithmetic sum of two numbers means that the sum of numbers […]

Absolute error of a measurement is the difference between the measured value of an object and its true value. When we take the measurement of an object, it is possible that the measured value is either a little more or a little lower than its true value, that is, an absolute error has occurred. For […]

In most of the everyday situations, we do not need to use highly sensitive measuring devices (instruments). the accuracy of our measurement depends on the purpose for which we use the information. Example: Suppose someone uses a compass as a guide in going from one end of the school to the other. It would not […]

Estimation is very useful especially when someone wishes to know whether he/ she has arrived at a logical solution to a problem under study. It is useful to learn about how to estimate the total sum of a bill to avoid immediate overpayments. For example, one can estimate the total amount of a shop (supermarket) […]

A bivariate relationship is defined by the joint distribution of the two associated random variables. Contingency Tables Let and are two categorical response variables. Let variable have levels and variable have levels. The possible combinations of classifications for both variables are . The response of a subject randomly chosen from some population has a probability […]

In R language, the packages can have namespaces, and currently, all of the base and recommended packages do except the dataset packages. Understanding the use of namespaces is vital if one’s plan to submit a package to CRAN because CRAN requires that the package plays nicely with other submitted packages on CRAN. Namespaces ensure that […]

In R Language, a vector is the simplest data structure. A vector in R is also an object that contains elements having the same data type. To create a vector (say ‘x’) of the same type (say double) of elements consisting of five elements one can use c() function. For example, Creating a vector in […]

Reading and Writing Data in R Reading Data in R For reading (importing) data into R following are some functions. read.table(), and read.csv(), for reading tabular data readLines() for reading lines of a text file source() for reading in R code files (inverse of dump) dget() for reading in R code files (inverse of dput) […]

In R language, list is an object that consists of an ordered collection of objects known as its components. A list in R Language is a structured data that can have any number of any modes (types) of other structured data. That is, one can put any kind of object (like vector, data frame, character […]

The R program’s structure is similar to the programs written in other computer languages such as C or its successors C++ and Java. However, important differences between these languages and R are (i) R has no header files, (ii) most of the declarations are implicit, (iii) there are no pointers in R, and (iv) text […]

The problem of multicollinearity plagues the numerical stability of regression estimates. It also causes some serious problem in validation and interpretation of the regression model.Â Consider the usual multiple linear regression model, , where is an vector of observation on dependent variable, is known design matrix of order , having full-column rank , is vector of […]

i appreciate you sir!

Hi Muhammad Imdadullah,

Thanks for posting a comment on my blog. I have included your blog in my blog feed. Keep up the good posts!

AsSalam O Alakam, This is MYaseen208. Please drop me an email. Thanks

A.o.a … imdad sb u did really nice work ,, uploading the statistical software … but i want to say that there is missing basic software like minitab ,,, spss … and Eview

I can’t gave download links of registered or priced softwares. I am sharing initially 100% softwares, most of them fulfills our many statistical needs and even solve many statistical problems. For minitab, SPSS, Eview I am trying to write their tutorial rather than sharing there pirated versions.

sir plz add interviw questions which mostly asked in interviwe

Its good idea, but initially its better if students appearing in different interviews provide some information about questions asked. Actually I am doing all the things myself. Its very difficult to maintain, run and update a website with unique contents.

A.A..

Hope you will be fine. I discoverd your site while I was just looking for SPSS model papers and some helping metrial regarding to mcqs on SPSS. It was a nice experience to see your hard work. It is quite appreciating. Please inform me if I would assist you in this regard.

Regards!

Sir, you are doing great job….really it is very helpful…..i want to say, thank you so much…kindly check the question # 3 in test 4 related the topic “regression and correlation”….i think the correct answer is option A….the line is parallel to x-axis….but the computer shows option D as right answer…. kindly check it out đŸ™‚

regards

W.A.

Thanks for liking the work.

Checked the question and found correct.

The question is related to equation such as y=k, which means that as x increases or decreases, y remains the constant hence line is parallel to the x-axis. One can also say that A line having a Zero Slope is Horizontal.

Thanks again for visiting and commenting

PLEASE MAIL ME AS ATTACHMENTS WITH ANSWERS MCQS ON BIOSTATISTICS AND LECTURES ON IT

BYE

SHAHID

You can download all available MCQS from sites.

Asslam o Alaikum,

sir would this material be enough for Public service Commission paper ( One paper commission) for Statistical Officer??

Good job…stay blessed

Salam Sir,

I Rahmat hassan from Gilgit student of statistics, Sir i would like to take some tips about FPSC b/c i visit your web page and gain much of information about my subjects.

Kindly help me sir

Thankyou Sir

AOA

Imdad Bhai , Good Job sir

Aslamoalaykum,

first of all thank you for providing a very good platform for the preparation of statistics, I think it’s the only Pakistani website which provides online test on Statistics.

I am preparing for the Public service examination and I am in need of all these MCQs set in one so I can get it printed, so please provide me the combined copy of all MCQs.

Thanking you in anticipation.

Regards,

Walaikum us salam,

Thank you for liking my website. All MCQs are downloadable. It is difficult for me to recompile them in a single file. However, I am thinking to create a paid improved MCQs file soon.
