Mean, Median and Mode are measures of...
Range and standard deviation are measures of....
What is Measures of Central Tendency and Measures of Dispersion (which are...)
What is a sample?
These three descriptive statistics show where the bulk of the data lie in a distribution
What is the mean, median and mode?
The "subject" of your research - the level/type of observation you are studying.
What is unit of analysis?
The hypothesis where there is not a relationship or difference
What is the null hypothesis?
The reason why inferential stats are called inferential
What is because you use them to infer something from a sample to a population
This is the statistical term for the level of confidence you want to have in your results
Age, population, area, savings, tax rates, water usage are all examples of these.
What are variables?
When you reject a hypothesis when in fact it is true, or when you accept a hypothesis when in fact it is false.
Type I or II error
These are at least four kinds of ways to gather data on a subset of a population
What are random, stratified, cluster, snowball, and convenience sampling (get 4 of the 5)
They were the best Star Trek Captain
Jean-Luc Picard!
This type of data can go up or down, but not precisely.
What is ordinal data?
Other terms for a Type 1 or Type II error
What is False Positive or False Negative
What is symmetrical or a normal distribution?
In multiple regression, you can include multiple of these.
Independent variables
These two letters of the alphabet symbolize independent and dependent variables in statistics
In looking at a relationship between two phenomena, this one is considered the outcome.
What is the dependent variable.
Sometimes called a critical value in inferential stats - give it a good guess or explanation.
Bonus (500!), what would the value be (exactly) if you wanted to be at least 95% confident that your result is not just random.
What is a T-score - basically the point above (or below, that is + or -) where you conclude a result is likely NOT random.
Bonus - what is 1.96 (or 2 is good enough)
This is the number of standard deviations from the mean (- and +) that encompass 95% of a normal curve in a data distribution
What is 2 on either side of the mean?
The 4 kinds of inferential statistical tests we cover in this class (we concentrate on 3 of the 4)
T-test, chi-square, correlation and regression.
The level of probability at which a null hypothesis is rejected.
Alpha
This is also called an explanatory variable
What is an independent variable?
