The lines in a histogram touch.
100
Another word for z-score.
What is a standardized score?
100
The values of the mean and standard deviation in a standard normal curve.
What is 0 (mean) and 1 (sd)?
200
Definition of percentile.
What is the percent of data that falls below a value?
200
The measure of center that is non-resistant and the measure of center that is resistant.
What is the mean and the median?
200
When graphing, the variable that goes on the y-axis and the variable that goes on the x-axis?
No, the dependent variable and the independent variable are not the correct answers.
What are the response variable (y) and the explanatory variable (x)?
200
State when normalcdf is used vs when invNorm is used.
What is normalcdf is used when you have the data (z-score or mean) and invNorm is used when you have the area under the curve as a percentage?

Color
Money
Temperature
Day of the week
Time
What is 2 categorical and 3 quantitative?
300
State the difference between discrete and continuous variables.
What is discrete variables are numerical values where counting makes sense (no decimals) and continuous variables are numerical values where decimals are appropriate (measuring)?
300
The 6 shapes used to describe distributions
What is the Unimodal, Bimodal, Uniformal, Symmetric, Left Skewed, Right Skewed,

What is median > mean?
OR
What is mean < median?
400
State the difference between a boxplot and a modified boxplot.
What is a boxplot includes the outliers and a modified boxplot identifies the outliers by marking them with dots/stars beyond the "whiskers"?
400
Three measures of data that have to be equal in a normal distribution.
Mean, median, mode
