All of the following are measures of central tendency except:
a. Range
b. Mode
c. Median
d. Mean
a. Range
What is the value of the mean for the following set of scores?
Scores: 5, 6, 10, 10, 9
a. 8.0
b. 10.0
c. 7.5
d. 9.0
a. 8.0
For which of the following sets of data would the mean be the most appropriate description of central tendency? (Hint: You should not need a calculator for this)
a. 1, 1, 1, 1, 4, 4, 4, 4, 4, 8, 9, 10, 11, 13, 15
b. The mean value would be equally descriptive of each of these data sets
c. 1, 3, 4, 5, 7, 8, 9, 11
d. 1, 3, 6, 7, 8, 65
c. 1, 3, 4, 5, 7, 8, 9, 11
What is the median for this data set: 1, 10, 5, 5, 11, 7
a. 6.5
b. 6.0
c. 5.0
d. 7.0
b. 6.0
When would be the best scenario to use the median?
a. The data set contains at least one significant outlier
b. There are two modes in the set
c. There are over 50 observations in the data set
d. The behavioral observations are not independent
a. The data set contains at least one significant outlier
Mode is the only measure of central tendency that can be used for what type of data?
a. Interval
b. Ratio
c. Ordinal
d. Nominal
d. Nominal
Variability essentially measures how the scores are _____ in terms of one another.
a. spread out
b. nominally distributed
c. ordered
d. related
a. spread out
The range of a set of data is not very useful for analyzing variability because:
a. Range can only be computed for full populations, not sample data sets
b. Regardless of the data set size, the range only accounts for two data point values
c. For any given data set, range values vary within that set
d. Range is a measure of central tendency, not variability
b. Regardless of the data set size, the range only accounts for two data point values
The range is typically calculated as the (highest value in a data set) minus (the lowest value in that set) (i.e., High – Low = Range). However, Dr Sigurdsson presented another way to derive the range for the purposes of some statistical calculations. What is the formula for this second method, which was the focus Dr. Sigurdsson’s discussion on range in the lecture?
a.
(Highest value) MINUS (the lowest value) PLUS 1
High – low + 1 = Range
b.
(Highest value MINUS the mean) PLUS (lowest value PLUS the mean)
(High – mean) + (low + mean) = Range
c.
(Highest value PLUS the lowest value) DIVIDED by 2
(High + Low) / 2 = Range
d.
The total SUM of (each data value) MINUS (the mean)
(Value 1 – mean) + (Value 2 – mean) +… (Value N – mean) = Range
a.
(Highest value) MINUS (the lowest value) PLUS 1
High – low + 1 = Range
When you calculate the sum of the deviations away from the mean of all scores in a distribution, that sum is always…
a. N
b. N-1
c. 1
d. 0
d. 0
The probability for any event ranges from X to Y .
a.

Y = 1
b.
X = 0
Y = 3
c.
X = Yes
Y = No
d.
X = 1
Y = 2
a.
X = 0
Y = 1
We use samples to make inferences about ________
a. replacements
b. samples
c. populations
d. biases
c. populations
Of the z-score values provided below, which one represents the greatest distance from the mean on the right-hand side of the distribution?
a. z = -2.00
b. z = +2.00
c. z = +1.00
d. z = -1.00
b. z = +2.00
Z-scores may only be calculated if:
a. Conclusions about the population are designed to be tentative
b. Every value is known for the entire population
c. The sample size of the population has no more than thirty
d. At least half of the population is included in the sample
b. Every value is known for the entire population
