Claim - (CORRECT ANSWER)An assertion, usually supported by evidence; an assertion about truth
Evidence - (CORRECT ANSWER)Information related to the accuracy of a claim
Reasoning - (CORRECT ANSWER)The process of logically relating evidence to a claim
Variable - (CORRECT ANSWER)A characteristic or quantity that changes according to the situation
Median - (CORRECT ANSWER)The central value in an ordered set of numbers
Maximum - (CORRECT ANSWER)The highest value in a set of numbers
Minimum - (CORRECT ANSWER)The lowest value in a set of numbers
Frequency - (CORRECT ANSWER)The number of times that a value within a range was observed
Relative frequency - (CORRECT ANSWER)The proportion of times that a value within a range was
observed
Relative frequency calculation - (CORRECT ANSWER)frequency/sum of all frequencies
Probability - (CORRECT ANSWER)A mathematical function that enables one to calculate the probability
of observing a value within any range

, 2
The mean of a normal probability distribution - (CORRECT ANSWER)A parameter that represents the
expected value of a variable
The standard deviation of a normal probability distribution - (CORRECT ANSWER)A parameter that
represents the uncertainty in the value of a variable
Calculating a standard deviation - (CORRECT ANSWER)1. Calculate each score's deviation (distance form
the mean)
2. Square each deviation
3. Compute the mean for the squared deviations (this is the variance)
4. Take the square root of the variance (this is the standard deviation)
Which condition must hold for a normal probability distribution to accurately describe a frequency
distribution? - (CORRECT ANSWER)Intermediate values occur more frequently than extreme values.
True or False? A normal probability distribution predicts the probability of observing any value in a
continuous range. - (CORRECT ANSWER)True
True or False? A normal probability distribution can have a shape with two peaks. - (CORRECT
ANSWER)False
True or False? A normal probability distribution can have an asymmetrical shape. - (CORRECT
ANSWER)False
True or False? For a normal probability distribution, a value that is one standard deviation above the
mean is equally likely as a value that is one standard deviation below the mean. - (CORRECT
ANSWER)True
, 3

deviation. - (CORRECT ANSWER)False

mean. - (CORRECT ANSWER)True
True or False? For a normal probability distribution, the likelihood of observing a value equal to the
mean depends on the standard deviation. - (CORRECT ANSWER)True
Which statement best defines inductive reasoning? - (CORRECT ANSWER)the process of using specific
data to construct a general model
Which statement best defines deductive reasoning? - (CORRECT ANSWER)the process of using a general
model to predict a specific outcome
Sum of squares - (CORRECT ANSWER)A measure of the deviations between observed values of a variable
and the mean
For a normal probability distribution, which of the following quantities represents the best value of the
mean? - (CORRECT ANSWER)The sum of observations divided by the number of observations
Which of the following parameters of the normal probability function equals the average deviation from
the most likely value of the variable? - (CORRECT ANSWER)standard deviation (σ)
True or false? To estimate the best value of the mean, one must know the standard deviation. -
(CORRECT ANSWER)False
