    Factual questions (1 point each-10 points) No lengthy answers
    1. Suppose that on a 100 item multiple choice test almost all students scored
    between 95 and 100 but a small scattering number of participants scored as
    low as 20.When plotted as a curve, the distribution will show what type of a
    curve?
    2. If all participants in a group have the same score, what is the value of the
    standard deviation of the scores?
    3. If a difference between two variables is declared to be statistically
    significant, what decision is being made about the Ho?
    4. The researcher commits what type of an error when she/he fails to reject
    the Ho which incorrectly states that there is no difference between the
    population means?
    THE FOLLOWING QUESTIONS ARE BASED ON THE TABLES
    BELOW (I &5 &VI). REFER TO SPECIFIC TABLE WHEN YOU
    ANSWER THE QUESTIONS.
    Answers should be appropriate for the points
    Question for Table 1
    1 (a) what values for 'preferences' are listed for each measurement tool?
    Name each one
    (b) Are the differences in 'preference' values statistically significant?
    (c) What statistical test is used to test the data?
    (d) What level of significance is used?
    Question for Table 5 (10 points).
    2. (a) what is the value of the Pearson' r' for the relationship between
    'quadriceps strength' and the 'side step test? Explain clearly to justify your
    answer.
    (b) I s the 'r' value significant? Provide a rationale for your answer
    Questions for Table VI
    3. (a) How many groups were in the samples? and what are the groups
    (b) What t' ratio listed in the table had the largest 'p' value?
    (c) What does the result (answer to b) indicate?
    (d) Are the results statistically significant? Provide a rationale for your
    answer
    (e) Is this an parametric statistic or non parametric statistic?
    Explain the difference between two
