You reject a null hypothesis. The null is actually true. You made this.
What is a Type I error?
Simple linear regression is based on this high-school formula.
What is Y = mX + b?
To use logistic regression, your outcome must be of this type.
What is binary?
Chi square test compares these.
What are frequencies (observed and expected)?
He is the only person to date to be inducted three times to the Rock and Roll Hall of Fame in Cleveland, OH.
Who is Eric Clapton (The Yardbirds 1992, Cream 1993, Solo 2000)?
You failed to reject a null hypothesis when it was really false. You made this.
What is a Type II error?
The outcome in linear regression must be at this kind of measurement level.
What is ordinal (some >5 categories) or continuous?
In logistic regression, your predictors must be of this type.
What is any type (continuous, categorical, ordinal, binary)?
A two-sample chi-square test is better known as this.
What is a test of independence?
Taking her 16 years of her career, she is the only Latina to have won an Emmy, a Grammy, an Oscar, and a Tony (commonly known as EGOT).
Who is Rita Moreno?
You fail to reject the null hypothesis when it was actually true. You just made this.
What is a correct decision?
When you include multiple predictors in ANOVA, you have a factorial ANOVA. When you do the same for linear regression, you have this.
What is multivariate linear regression?
In logistic regression, you will not compare means, but you will predict this of your outcome.
What is the probability distribution (aka the Bernoulli distribution)?
A one-sample chi-square test is better known as this.
What is the goodness-of-fit test?
These two countries will be participating for the very first time in their history in the 2018 FIFA World Cup in Russia.
What are Iceland and Panama?
rMP(100) = -0.46, p<0.01
You can explain this much variance of M by the variance of P.
What is 21.1%?
Linear regression is a parametric method. Thus, it assumes these.
What are normality, homoskedasticity, and correlation between predictor and outcome?
In logistic regression, the exponentiated beta coefficient is equal to this.
What is the odds ratio?
Calculators out!
A test of independence had a result of X2(3) = 8.4, p < 0.05. There were two columns in the contingency table. You can know there were this many rows.
What is 4?
This bacterium made it to the headlines after contaminating lettuce from Arizona and causing outbreaks in many states.
What is Escherichia coli?
A statistically significant correlation coefficient can show the strength and direction of the effect. However, it cannot prove this.
What is causality?

What is 65,000.00?
You obtain an OR = 3.2 [95% CI 2.2, 4.2]. You make this decision about the null hypothesis.
What is reject it?
The proportion of males and females in this classroom makes the X2 value very high. This can be interpreted as this type of distribution.
What is unequal (more so than by chance alone)?
