◉ (Module 2) An academic adviser wanted to investigate the amount
of money spent by students on textbooks. She randomly sampled 25
students and asked how much they had spent on textbooks. Which
of the following would be an appropriate graph to make of the
sampled data?
a. dotplot
b. stemplot
c. histogram
d. all of the above. Answer: d. all of the above
◉ (Module 3) If the mean is equal to the median, which of the
following is true?
a. There is a mistake. The mean can not equal the median.
b. The data is probably symmetric.
c. The data is probably skewed.
d. The data has to be bell shaped distributed. Answer: b. The data is
probably symmetric.
,◉ (Module 3) Suppose that you had the following data set.
500 200 250 275 300
Suppose that the value 500 was a typo, and it was suppose to be
negative (-500). How would the value of the standard deviation
change?
a. It would increase.
b. It would decrease.
c. It would stay the same.
d. Unable to be determined.. Answer: a. It would increase.
◉ (Module 3) Find the sample standard deviation of the following
data set, using the statistical functions on your calculator.
0.2315 0.4725 0.87650.4865 0.5326 0.7976
a. 0.2358
b. 0.2153
c. 0.5662
,d. 0.1895. Answer: a. 0.2358
◉ (Module 3) Scores on an exam follow an approximately bell
shaped distribution with a mean of 76.4 and a standard deviation of
6.1 points. Approximately, what percentage of the data is between
64.2 points and 88.6 points?
a. 68%
b. 95%
c. 99.7%
d. 50%. Answer: b. 95%
◉ (Module 3) Match each term on the left column with the
appropriate description from the right column description. Each
answer choice will only be used one time.
a. mean
b. median
c. mode
d. range
e. variance
f. standard deviation
, 1. Distances from the data points to this measure of center always
add up two zero
2. This measure of center always has exactly 50% of the
observations on either side
3. This measure of center represents the most common observation,
or class of observations
4. This measure of spread is affected the most by outliers
5. Measure of spread around the mean, but its units are not the same
as those of the data points
6. Is smaller for distributions where the points are clustered around
the middle. Answer: a. mean = (1) Distances from the data points to
this measure of center always add up two zero
b. median = (2) This measure of center always has exactly 50% of
the observations on either side
c. mode = (3) This measure of center represents the most common
observation, or class of observations
d. range = (4) This measure of spread is affected the most by outliers
e. Variance = (5) Measure of spread around the mean, but its units
are not the same as those of the data points
