Statistical vs. Non-Statistical
A question that has only one factual answer
What is a non-statistical question?
When the values in our data set are numbers
What is numerical data?
The shape of distribution when we have two peaks on our graph (two values with the most amount of data)
What is bimodal?
This type of graph is often confused with bar graphs
What is a histogram?
This represents the "middle" of our data set
What is median?
This collects data, and the answers have variability
What is a statistical question?
When the values in our data set are categories
What is categorical data?
The shape of our distribution when we have the same amount of data for every value in our set
What is uniform?
The Minimum, Q1, Median, Q3, and Maximum are displayed right on this graph
What is a box plot?
The mode of the data set below is _______:
21, 21, 22, 25, 26, 26, 27, 28, 28, 28, 28, 29, 30
What is 28?
"How many pages is the book Twilight?" is an example of a ___________ question
What is a non-statistical question?
"How many animated movies did Algebra I students watch this past year?" is a question that would collect _________ data
What is numerical data?
The mean and median are equal to each other when our data has this type of distribution
What is symmetric?
When a section of our box plot appears really long, this means our data is ___________
What is spread out?
To find the mean of a data set, we must:

+100 Bonus if answer given was skewed right
This graph is the only type among the three that shows us every value of data
