Chi-square test is a non-parametric test. The assumption of normal distribution in the population is not required for this test. The statistical technique chi-square can be used to find the association (dependencies) between sets of two or more categorical variables by comparing how close the observed frequencies are to the expected frequencies. In other words, […]

Mean: Measure of Central Tendency The measure of Central Tendency Mean (also know as average or arithmetic mean) is used to describe the data set as a single number (value) which represents the middle (center) of the data, that is average measure (performance, behaviour, etc) of data. This measure of central tendency is also known […]

Probability sampling In probability each unit of the population has known (non-zero) probability of being included in the sample and samples are selected randomly by using some random selection method. That’s why, probability sampling may also be called random sampling. In probability sampling reliability of the estimates can be determined. In probability sampling, samples are […]

It is often required to collect information from the data. There two methods for collecting the required information. Complete information Sampling Complete Information In this method the required information are collected from each and every individual of the population. This method is used when it is difficult to draw some conclusion (inference) about the population […]

Research is inquiry. It is a process of discovering some new knowledge, that involves multiple elements such as theory development and testing, empirical inquiry, and sharing the generated knowledge with others such as experts and colleagues. A short description about elements of theory is: Theory is a set of ideas and perceptions that helps people […]

Question 1: How can I retrieve (load) the work that is saved using history function in R? Answer: The loadhistory() function will load an “.Rhistory“file. > loadhistory(“d:/file_name.Rhistory”) This function will load file named “file_name.Rhistory” from D: drive. The other way may be to access .Rhistory file through the file menu. For this click File and … Continue reading “R Basics”

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 🙂

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
