R Studio

100

This phrase was the first thing we created with R Studio in Lab 1

 HELLO WORLD

200

The "paper" on which we type our code 

Script

300

The window in which we can observe our data

The environment window

400

Which character do we use to type a comment in R Studio?

# Hashtag, Pound sign, etc.

500

We would use this command when creating a graph

plot(x, y)

Experiments and Research

100

The two groups that take part in an experiment

Control group, experiment group

200

A statistical result is this if it applies to populations beyond the sample of the analysis

Generalizable

300

This type of study uses data gathered from an environment that is not controlled by a researcher

Observational study

400

The two types of validity concerning research findings

internal validity, external validity

500

One of the greatest threats to internal validity and establishing causation between variables

Endogeneity

Regressions

100

How many variables are in a simple regression?

2

200

This term contains factors that are not captured by the model

Error Term

300

The name for the point at which the regression line crosses the Y-Axis

Intercept/Constant

400

This variable is multiplied by the slope coefficient in a regression equation

Independent variable

500

What does B1 tell us?

The change in the dependent variable for each 1 unit increase in the independent variable

Data

100

This describes the spread of our data

Standard deviation

200

A graph depicting the relationship between two variables using points/dots

Scatterplot

300

This is where we describe the sources of our variables, and any changes we made to them

Codebook

400

This is where we document how we gathered and organized our data

Replication files

500

We describe a statistical result as this if the result doesn't change when the model changes

Robust

Miscellaneous

100

The term B0 in a regression equation

Intercept/constant

200

The process of determining the experimental value of the key independent variable based on a random process

Randomization

300

If an independent variable is endogenous, it is correlated with this

Error term

400

Statistical parameters that summarize your sample data

Summary statistics

500

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
