In an experiment, this is the general idea gathered from the observation that predicts an outcome.
What is Thesis/Theory?
Unhindered observations of the natural environment.
What is naturalistic observation?
In an experiment, this is the group that receives the placebo.
What is control?
Provide the 3 keys to a valid experiment (besides that it must be repeatable).
What is:
1) reliable
2) valid
3) standardized
These are statistics from which an educated guess is made about the data.
What are inferential stats?
This is a two-variable graph in which a slope may be used to infer a positive, negative, or no correlation between the two variables.
What is a scatterplot?
In an experiment, this is a testable prediction about that outcome.
What is the hypothesis?
Study of an individual person or group in hopes of discovering a universal truth.
What is a case study?
Choosing a random portion of people from a given population for an experiment.
What is random selection?
These are statistics in their base form, as raw data and numbers.
What are descriptive stats?
Provide the four basic rules established here in the US that protect participants.
What are:
1) Fully De-brief
2) Confidential
3) Informed Consent
4) No Pain
With statistics, besides the mode, mean, median, and range, this is the average measure of variance between scores around the mean.
What is the standard deviation?
These are detailed instructions and procedures in order to replicate the experiment.
What are operational definitions?
A study in which neither the participants nor experimenters know which group received the treatment or placebo.
What is a double-blind?
Randomly distributing the portion of the population into experimental groups to avoid bias.
What is random assingment?
The term refers to the typical/central value for a probability distribution; colloquially, these are called averages.
What is a central tendency?
This type of study is an observational research method in which data is gathered for the same subjects repeatedly over a period of time.
What is a longitudinal study?
Provide the two institutions that provide psychological guidelines for studies in the US and UK.
What are:
1) BPS
2) APA
Studies that attempt to discover if one factor causes another as they often come in tandem (together).
What is correlation?
In an experiment, this is the group that receives the treatment.
What is experimental?
This is the statistical term that measures how strong a relationship is between two variables. The number itself ranges from -1 to 1 and represents the correlation between two variables.
What is the correlation coefficient?
Double Jeopardy:
1) Regarding statistics, this is a frequency distribution with a rightward skew due to its long tail in the positive direction on a number line.
2) Regarding statistics, this is a frequency distribution with a leftward skew due to its long tail in the positive direction on a number line.
What are:
1) positive skew
2) negative skew

What is the IACUC?
This type of study is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time.
