R Studio
This phrase was the first thing we created with R Studio in Lab 1
HELLO WORLD
The two groups that take part in an experiment
How many variables are in a simple regression?
2
This describes the spread of our data
Standard deviation
The term B0 in a regression equation
Intercept/constant
The "paper" on which we type our code
Script
A statistical result is this if it applies to populations beyond the sample of the analysis
Generalizable
This term contains factors that are not captured by the model
Error Term
A graph depicting the relationship between two variables using points/dots
Scatterplot
The process of determining the experimental value of the key independent variable based on a random process
Randomization
The window in which we can observe our data
This type of study uses data gathered from an environment that is not controlled by a researcher
Observational study
The name for the point at which the regression line crosses the Y-Axis
Intercept/Constant
This is where we describe the sources of our variables, and any changes we made to them
Codebook
If an independent variable is endogenous, it is correlated with this
Error term
Which character do we use to type a comment in R Studio?
# Hashtag, Pound sign, etc.
The two types of validity concerning research findings
internal validity, external validity
This variable is multiplied by the slope coefficient in a regression equation
Independent variable
This is where we document how we gathered and organized our data
Replication files
Statistical parameters that summarize your sample data
Summary statistics
We would use this command when creating a graph
plot(x, y)
One of the greatest threats to internal validity and establishing causation between variables
Endogeneity
What does B1 tell us?
The change in the dependent variable for each 1 unit increase in the independent variable
We describe a statistical result as this if the result doesn't change when the model changes
Robust
This type of experiment occurs when a researcher identifies a situation in which the values of the independent variable have been determined by a random or, at least an exogenous, process
Natural experiment
