Question 1

Which of the following is false regarding statistical analyses?

Accepted Answer

All the statements (A, B, and C) correctly describe aspects of statistical analyses: univariate statistics describe single variables, bivariate statistics explore associations between two variables, and multivariate statistics examine effects of multiple variables on a dependent variable.

Question 2

Which of the following can determine the causality between variables?

Accepted Answer

Multivariate statistics can determine the causality between variables by analyzing the relationship between multiple variables simultaneously, allowing for the assessment of how changes in one variable may cause changes in another.

Question 3

Which of the following is false regarding measures of central tendency?

Accepted Answer

The mean is not always the exact middle number in a distribution; it is the average of the numbers. The median, not the mean, is the exact middle number when the numbers are arranged in order.

Question 4

The following numbers are the exam results of 10 students:
70, 75, 75, 75, 80, 85, 95, 95, 100, 100
What is the mean?

Accepted Answer

The answer of The following numbers are the exam results...

Question 5

The following numbers are the exam results of 10 students:
70, 75, 75, 75, 80, 85, 95, 95, 100, 100
What is the mode?

Accepted Answer

The mode is the number that appears most frequently in a data set. In this case, 75 appears three times, more than any other number, making it the mode.

Question 6

The following numbers are the exam results of 10 students:
70, 75, 75, 75, 80, 85, 95, 95, 100, 100
What is the median?

Accepted Answer

The median is the middle value in a list of numbers. Since there are 10 numbers, the median will be the average of the 5th and 6th numbers when the numbers are arranged in order. The 5th and 6th numbers are both 80 and 85, so the median is (80 + 85) / 2 = 82.5.

Question 7

The following numbers are the exam results of 10 students:
70, 75, 75, 75, 80, 85, 95, 95, 100, 100
What is the range?

Accepted Answer

The range is the difference between the highest and lowest values in a set of numbers. Here, it is 100 - 70 = 30.

Question 8

The following numbers are the exam results of 10 students:
70, 75, 75, 75, 80, 85, 95, 95, 100, 100
What is the variance?

Accepted Answer

The variance is calculated by finding the mean (average) of the numbers, subtracting the mean from each number, squaring the result, finding the average of those squared differences, and finally rounding if necessary. The mean of these numbers is 85. The squared differences from the mean are 225, 100, 100, 100, 25, 0, 100, 100, 225, 225. The average of these squared differences is 133.33, which is the variance.

Question 9

The following numbers are the exam results of 10 students:
70, 75, 75, 75, 80, 85, 95, 95, 100, 100
What is the standard deviation?

Accepted Answer

The answer of The following numbers are the exam results...
