Question 1 1 / 1 pts What is the range in the following data set: 10, 13, 15, 29, 35, 40, 12, 21, 19, 31. 10 40 20 Correct! 30 That is correct. The range is the distance between the largest number and the smallest number in an ordered data set. In this case, you need to arrange the values from smallest to largest first, then subtract the smallest number from the largest number (40-10) = 30. Question 2 1 / 1 pts What does it mean if you have a large standard deviation? Your data needs to be re-organized. Your data is not valid. Your data clustered around the mean. Correct!

Your data is more spread out. That is correct. Large standard deviation means your data is more spread out relative to a data with smaller standard deviation. Question 3 0 / 1 pts (True) or (False)? Inferential statistics should be used at all times in order to generate meaningful insights into a data set. You Answered (True) Correct Answer (False) Try again. Using inferential statistics on a non-probability sample to make broad generalizations will be problematic. If you would like to learn more about this topic, refer to Module 4. Question 4 0 / 1 pts Which of the following descriptions about the mode is correct? It can also be used as a measure of correlation. You Answered The researcher must use statistical software packages to calculate the mode. Correct Answer It can be thought of as the most common and popular option in a data set.

It is a superior measure of central tendency than mean and median. Actually, try again. The mode is the value that occurs the most frequently in a data set. It can also be thought of as the most common and popular option in a data set. If you would like to learn more about this topic, refer to Module 4. Question 5 0 / 1 pts The measure that indicates how far each number in a data set is from the mean is called ________. Correct Answer variance You Answered range dispersion diffusion Actually, try again. Variance measures how far each number in a data set is from the mean. If you would like to learn more about this topic, refer to Module 4. Question 6 0 / 1 pts Which of the following measures of central tendency is susceptible to the influence of extreme values and outliers? Median You Answered

Standard deviation Range Correct Answer Mean Try again. Mean is susceptible to the influence of extreme values and outliers. If you would like to learn more about this topic, refer to Module 4. Question 7 1 / 1 pts Which of following is not a measure of central tendency? Mean Correct! Variance Mode Median Correct. Variance is not a measure of central tendency. Question 8 1 / 1 pts (True) or (False)? Measures of dispersion indicate how “spread out” the data is in a data set. Correct!
