Don’t forget to mention the MCQs Statement (or Screenshot), because MCQs and their answers are generated randomly

Basic statistics deals with the measure of central tendencies (such as mean, median, mode, weighted mean, geometric mean, and Harmonic mean) and measures of dispersion (such as range, standard deviation, and variances).

Basic statistical methods include planning and designing the study, collecting data, arranging, and numerical and graphically summarizing the collected data.

Basic statistics are also used to perform statistical analysis to draw meaningful inferences.

A basic visual inspection of data using some graphical and numerical statistics may give some useful hidden information already available in the data. The graphical representation includes a bar chart, pie chart, dot chart, box plot, etc.

Companies related to finance, communication, manufacturing, charity organizations, government institutes, simple to large businesses, etc. are all examples that have a massive interest in collecting data and measuring different sorts of statistical findings. This helps them to learn from the past, noticing the trends, and planning for the future.

1. Dear Nickson!
The MCQs related to grouped data is mixed within the Basic MCQs test. There are 10 Quizzes under the category of the “BASIC STATISTICS” MCQS test. However, I am trying to update more.

I have submitted a quiz, the answers are shown. See the screenshot.

1. AOA Sir

Jazak Allah

1. It becomes very difficult to identify that about which question you are asking about. There is seven MCQs Test for Basic Statistics and for online test most of the questions are randomly generated. However, for I traced option having 2.33 from the text MCQs, and found that answer is correct.
Perhaps the question is related to the standard deviation of 2, 4, 6, and 8. And the standard deviation of 4, 6, 8, and 10.
If this is not the MCQ you are asking about then it is better to mention the test number and question rather just mentioning the 1st question.

2. Question 25. Ans should be “None of these”… since that sum will result into final answer “4”… or question should be corrected.. plz reply if m wrong

1. There was a typo in question which is corrected now. Thank you.

Next time please mention the test name (or question). It takes a lot of time to search the question just on the bases of options.

3. thankyou so much. Its really informative webiste. Around 50-60 percent questions in fpsc paper comes from here.

8. This site is so helpful,thank you so much MR Muhammad,I can now final say i am ready for a statistics test

9. Q22 on this of Test 3 “MCQs about Measure of Dispersion I” is wrong . instead of 2.33 this should be 2.58

10. first of all i congratulate you for having wonderful for we people. i will bring you to notice if any error i found being new learner with hope a good response. meanwhile the scoring of test is not accurate, for example i conducted basic test one of descriptive statistics, i obtained right only 17 questions but result shows that i obtained right questions 26.

1. In MCQs Basic Statistics 3 test, Q9 is “Lowest value of variance can be” and its answer is 0 which is correct.
and Q22 is “The percentage of values lies between $overline{x} pm 2sigma$” and its answer is 95.45% which is also correct.

Please mention the actual questions or tell what is wrong with these questions.
