Stats stuff

2. includes all individuals or objects of interest
6. Expiriment in which the participants are not told which group they are in
8. two variables are casually associated if changing the value of the explanatory variable influences the value of the response variable.
10. The design of a statistical study shows bias if it would consistently underestimate or consistently overestimate the value you want to know
11. a third variable that is associated with both the explanatory variable and the response variable.
13. Divides the cases into groups or categories
14. letting your sample be comprised of whoever chooses to participate
18. a measure that is not impacted by an outliers or extreme values
20. The largest data value
21. all the cases that we have collected data on
22. The average of the data values
24. The smallest data value
25. Using a chance process to determine which members of a population are included in the sample each member of the population has an equally likely chance of being chosen
27. predicted y-value when x=0
28. Facts and statistics collected together for reference or analysis.
29. increase in predicted y for every unit increase of x
31. a study in which the researcher does not actively control the value of any variable, but simply observes the values as they naturally exist.
32. Measures the outcome of the study

1. Helps to predict changes or explain the response variable
3. occurs when an individual chosen for the sample can’t be contacted or refuses to participate.
4. the process of using data from a sample to gain information about a population
5. neither the participants or the people who are interacting with the participants and recording the results of the response variable also do NOT know who is in which group.
7. two variables are associated if values of one variable tend to be related to values of the other variable.
9. often people will experience the effect they think they should be experiencing, even if they aren’t actually receiving the treatment.
12. the measure of the strength and direction of a linear line
15. occurs when some members of the population cannot be chosen in a sample.
16. Measures a numerical quantity for each case
17. The middle value when the the values are ordered from least to greatest
19. The practice or science of collecting and analyzing numerical data in large quantities
23. a study in which the researcher actively controls one or more of the explanatory variables. Also, some sort of treatment is administered.
26. occurs when the method of selecting a sample causes the sample to differ from the population in some relevant way.
30. an observed value that is notable distinct from the other values
