What are all three measures of central tendency?
Mean

What is a construct?
An explanatory variable which is not directly observable
100
What is confirmation bias?
The tendency to interpret new evidence as confirmation of one's existing beliefs or theories

Define reliability and validity
Reliability: How consistently a measure produces the same outcome
Validity: How well a measure actually captures what is claims to represent

What is Interval?

What is the difference between the mean and the median?
The mean is the average of all the data points, the median is the middle of all of the data points

What’s an operational definition?
A way of defining the measurement of a phenomenon that is not directly measurable

I am the variable that gets MANIPULATED in an experiment
What is the Independent Variable
300
Calculate the mean and median of the following dataset:
1 6 18 24 33 76 98 114
Mean: 46.25
Median: 28.5
300
What is the difference between experimental and non-experimental methods?
In an experiment, we manipulate the independent variable and we can draw causal conclusions. In non-experimental methods, nothing is manipulated and we cannot make causal conclusions (i.e. "this caused that").

What is the difference between basic and applied research?
Basic research is the practice of understanding fundamental questions and fill in knowledge that we don't have.
Applied research is the use of basic research to solve real world problems.

Define the different types of reliability
Interrater reliability
Test-Retest
Internal Consistency

What is the difference between a discrete and a continuous variable?
Discreet: Whole integers (ex. number of siblings)
Continuous: any number (Weight)
400
When the distribution is skewed to the right what happens to the mean, median, and mode?
The mode and median are not affected. The mean becomes higher.
400
What is a frequency distribution?
Frequency distribution is a representation, either in a graphical or tabular format, that displays the number of observations within a given interval

What is construct validity?
The degree to which a test measures what it claims to be measuring
500
I am the outcome or response variable.
Dependent Variable.

What is the difference between variance and standard deviation?
The standard deviation is the square root of the variance.
500
What are degrees of freedom and how do we calculate it?
Degrees of freedom are the values are free to vary when we calculate statistics
(N - 1)

What’s a between-subjects design versus a within-subjects design?
500
What are ceiling and floor effects?
A ceiling effect is when a high proportion of subjects in a study have maximum scores on the observed variable. A floor effect is when a high proportion of subjects have the minimum scores on the observed variables.
