The two main types of descriptive stats we are covering in this class

What is Measures of Central Tendency and Measures of Dispersion (which are...)

100
A subset of a population

What is a sample?

100

These three descriptive statistics show where the bulk of the data lie in a distribution

What is the mean, median and mode?

100

The greatest net benefit

What is the fundamental rule of CBA?

100

The hypothesis where there is not a relationship or difference

What is the null hypothesis?

200
The type of data that go across a unit of analysis, the type of data that go across time, and the type of data that do both
what are cross-sectional, time-series and panel data
200

The reason why inferential stats are called inferential

What is because you use them to infer something from a sample to a population

200

This is the statistical term for the level of confidence you want to have in your results

What is alpha?
200
The first step in a CBA

What is identify costs and benefits

200

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

300
The kind of distribution you have when the mean is much greater than the median
What is a positively skewed distribution?
300

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)
300

This type of data is also called continuous

What is interval or ratio (Berner will use the term interval to capture both)

300

The costs of not doing something.

What are opportunity costs?

300

Other terms for a Type 1 or Type II error

What is False Positive or False Negative

400
The kind of distribution that is equal on both sides of the mean

What is symmetrical or a normal distribution?

400

In multiple regression, you can include multiple of these.

Independent variables

400

These two letters of the alphabet symbolize independent and dependent variables in statistics

What are X and Y?
400

How you might estimate a cost or benefit for something that is hard to put a direct $ value on, like having a park across the street.

What is willingness to pay?
400

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.  

A T-score, a Z-score - basically the point above (or below, that is + or -) where you conclude a result is likely NOT random.


Bonus - what is 1.96?

500

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?

500

The four kinds of inferential stats we will cover in this class

T-test, chi-square, correlation and regression.

500

The level of probability at which a null hypothesis is rejected.  

Alpha

500
Closing a problematic waste transfer station from one county to another.

What is an example of shifted costs?

500

Top pop song in 1999
