Basic statistics deals with the measures of central tendency (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.

    • 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.

    • 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.

    • Your provided reference of question in test 3 is not correct. Perhaps its question 3. Question 3 is correct as it says “The measure of dispersion is changed by a change of” and answer is “scale”.
