100
It can be made solely by having the five-number summary. It is good for comparing quantitative data.
What is a Boxplot?
100
The two measures of the center of a set of data.
What are mean and median?
100
68%, 95%, and 99.7% of the data lie inside the first, second, and third standard deviations, respectively, for an approximately normal distribution.
What is the empirical rule?
100
This is the test you use when the standard deviation of the population is unknown.
What is a T-Test?
200
Used to compare very large quantities of numbers. It often uses percentages in the y-axis.
What is a histogram?
200
In terms of a scatterplot, r represents these two details.
What are direction and strength?
200
P(A) + P(B) - P(A and B).
What is P(A or B)?
200
When you accidentally reject Ho when Ho is correct.
What is Type I Error?
300
This is the graph of the distance of each of the individual data away from the LSRL.
What is Residual Plot?
300
The level of confidence by which you choose to reject a Ho.
What is your alpha-level?
300
The four conditions for a binomial distribution.
What are success and fail, independence, set number of trials, and probability is constant?
300
The conditions to use this test include all expected counts be greater than or equal to 1 and no more than 20% of all the expected counts be less than 5.
What is the Chi-Square GOF Test?
400
Data is altered to become more significant through the use of some mathematical function such as power, roots, log, exponential, etc.
What is a transformation?
400
Events that have no outcomes in common and can never occur simultaneously.
What are disjoint or mutually exclusive events?
400
This should not be done because they can easily be inaccurate. It is when you predict using an LSRL outside the range of data.
What is extrapolation?
400
If a person found a 95% confidence interval to be (5,100) and they say "95% of the data falls between the numbers (5,100)" would they be correct? If not, what would be the correct way to say it?
"We are 95% confident that the true population mean is captured by the interval (5,100)" or "95% of all trials using this technique would give intervals that capture the true population mean".
