Consider the following example for a binomial distribution. Identify the value of "N."
1 You have a perfectly shuffled deck of 52 cards (containing 13 cards in each of the 4
different suits: hearts, clubs, spades, and diamonds) Given that you draw 5 cards, you
are interested in the probability that exactly 2 of them are diamonds.
2 What types of things can a histogram help us visualize?
Approximately every 3 in 100 parents homeschooled their children in 2011.
3
This is an example of what type of statistics?
4 Scatterplots are particularly important when discussing correlation.
, Don't know?

What types of things can a histogram MODALITY & QUARTILES VALUES
help us visualize?
Stem-and-Leaf plots are widely used FALSE
today
A boxplot shows the value 31 at the 25% IS LESS THAN 31
first quartile. What does this tell you?
Values beyond the lower and upper OUTLIERS
whiskers (the min and max values)
generally represent what?
Scatterplots are particularly TRUE
important when discussing
correlation.
Bar graphs are typically used to TRUE
represent values of one variable
across different levels of a
categorical variable.
Which of the following is NOT a VARIANCE
measure of central tendency?
Group A has a mean of 0 and a
median of 15
What is most likely true?
, Distribution A: mean = 0, median = 0, s Distribution A is more spread than B, but more likely
= 10 to be normally distributed
Distribution B: mean = 12, median = 22,
s=5
Which of the following is most likely
true?
Variance is the square root of FALSE
standard deviation
You have a large standard deviation. NORMALLY DISTRIBUTED & VERY SKEWED
Which of the following could be
true?
With a fair die, there is a 3 in 6 change PROBABILITY
of an even number being rolled.
Is this an example of probability or
statistics?
Approximately every 3 in 100 parents DESCRIPTIVE STATISTICS
homeschooled their children in 2011.
This is an example of what type of
statistics?
What type of statistics attempts to INFERENTIAL
make inferences about the unknown?
This approach to probability is often BAYESIAN
referred to as the subjectivist
approach.
