_______________________________. These are same to the sum of the range of
individuals in the corresponding row or column. - ANS-The cells in yellow display joint
frequencies*. These constitute the entire wide variety of instances that fall in each the
corresponding row and header.
4.
5. For example, information in the "Male" row and "With Autism" column counts the wide
variety of men with autism.

7. The information inside the inexperienced cells show marginal frequencies*. These are
same to the sum of the variety of individuals in the corresponding row or column. For
example, information within the "Totals" column and "Female" row indicates the overall
quantity of ladies within the examine. It may be useful to remember that marginal
frequencies appear within the margins of the desk.

10. 1. A health center is analyzing the effectiveness of one of a kind heartburn remedies
(Treatment A and Treatment B) administered every day for a week. The results are
measured after one week of treatment, with the aid of putting a affected person into one
of companies: heartburn subsided OR heartburn remained. Which numerical degree
could be used to research the information?
11.
12. A. Correlation coefficient
13.
14. b. Five-quantity precis
15.
16. c. Median
17.
18. d. Conditional probabilities - ANS-Correct. The answer is d. Both variables are specific
(C→C) so we will use a -manner desk. Therefore, our numerical degree will be
conditional possibilities.
19. 1) Strong Positive Linear Correlation ( Lower left corner to upper right nook)

21. 2) Strong Negative Linear Correlation ( Upper left nook to decrease right nook) - ANS-
, 22. thirteen. When working with -variable records, if each variables are quantitative, what's
the maximum suitable choice to display the information?
23.
24. A) Side-via-facet boxplots
25. b) Scatterplot
26. c) Bar chart
27. d) Two-way frequency table
28. e) Histogram - ANS-Answer: B
29.
30. When working with two-variable records, if both variables are quantitative, a scatterplot
is the maximum suitable preference to display the facts.
31. Three) Very susceptible, correlation
32.
33. four) nonlinear or curvilinear association - ANS-
34. 4. Consider a examine on whether a sure remedy improves kidney feature in sufferers
with continual kidney disorder. The Glomerular Filtration Rate (GFR) become collected
for 2 organizations: a treatment institution and a placebo organization. The researchers
want to examine the middle 50% of the facts for each organizations. Which numerical
measure could discover the 2 values that 50% of the records falls among for each
businesses?
35.
36. A. Median
37.
38. b. Five-range summary
39.
40. c. Mode
41.
42. d. Joint Frequencies - ANS-four. Consider a examine on whether a positive remedy
improves kidney feature in sufferers with chronic kidney disorder. The Glomerular
Filtration Rate (GFR) was amassed for two organizations: a treatment organization and a
placebo group. The researchers want to evaluate the middle 50% of the records for each
businesses. Which numerical measure would discover the two values that 50% of the
data falls between for both corporations?
43.
44.
45. B. Five-quantity precis
46.
47. Correct. The answer is b. In this observe one variable is categorical and the alternative is
quantitative (C→Q) . The 5-range precis will show 5 essential statistical values: minimal,
most, first quartile, median, and 1/3 quartile. 50% of the facts falls among the primary(
Q1 ) and 1/3( Q3 ) quartile, so the researchers ought to observe the five-range precis to
decide the values for Q1 and Q3 for both companies, as these values outline the middle
50% of the data.
