These are the two types of data.
What are qualitative/categorical and numerical/quantitative?
This is another name for relative frequencies.
What are proportions?
These are the three types of measures of center.
What are mean, median, and mode?
This term describes the difference between an observed value and the predicted value given by a regression line.
What is the residual
This event is formed by combining two or more events.
What is a compound event?
Name the four subcategories of the types of data.
What are nominal, ordinal, discrete, and continuous?
This is a type of graph that uses frequencies for its vertical axis.
What is a frequency histogram?
These are the three types of numerical summaries.
What are measures of center, spread, and position?
In a linear regression equation, this value represents the predicted change in the response variable for each one-unit increase in the explanatory variable.
What is the Slope
This is a collection of all the possible outcomes of a probability experiment.
What is Sample Space?
This is a type of Statistics that organizes, displays, and describes data using tables, graphs, and numbers.
What is Descriptive Statistics?
This is a type of distribution in which the left and right sides form mirror images when divided down the middle.
What is a symmetric distribution?
This is the unit of measurement used to describe the Coefficient of Variation.
What is percentage?
In a regression model, this value tells us the strength and direction of the linear relationship between two variables.
What is the correlation coefficient (r)?
A fair die (numbered 1-6) is rolled. This is the probability that an even number comes up.
What is 0.5/50%?
This is a type of bar graph with the frequencies sorted from largest to smallest.
What is a Pareto Chart?
This lists all of the classes on the first column as intervals and the number of values that belong to each class on the second column.
What is a frequency distribution table?
This is the most used method of dispersion.
What is Standard Deviation?
If an LSRL has a slope of 2 and a y-intercept of 5, what is the predicted value of the response variable when the explanatory variable is 3?
What is 11?
A bag contains 8 red balls, 5 blue balls, and 7 green balls.
What is the probability of randomly drawing either a red ball or a blue ball from the bag?
What is 0.65?
Name the five types of sampling methods.
What are simple random, convenience, systematic, stratified, and cluster.
This is a graph formed by a line graph where the horizontal values are the midpoints of the distribution and the vertical values are either frequency, relative frequency, or percentage.
What is a Polygon?
A data set consists of the following five values: 12, 15, 20, 22, and 30. Calculate the mean and the standard deviation of this data set.
What is 21.8 (mean), and 6.53 std dev?
If a linear regression model has a correlation coefficient 𝑟 = 0.8, what is the coefficient of determination, and what does it tell us about the relationship between the two variables?
What is 0.64, means that 64% of the variability in the dependent variable is explained by the independent variable
This is the rule that states that as a probability experiment is repeated, the proportion of times that a given event occurs will approach its probability
What is the Law of Large Numbers?
