Definitions
What is the variable that is measured based on the changes caused by the independent variable?
Dependent Variable
What kind of study incorporates researchers purposely altering a variable and studying the results? Researchers usually use a control group and a testable group. These are usually randomized as well.
Experimental Studies
We have an entire student body and each kid participates in either a club, sport, or art. We give each kid a survey on if they like in person schooling or online. We look at the results from each group. What kind of sample is this?
Stratified-Random Sample
What concept do these features relate to? Objectivity, Verifiability, Unbiasedness, Experimentation, Reliability, Precision, Accuracy, Abstractness, Predictability. This kind of science seeks to disprove theories and looks to the future for its experiment results. This kind of science must be falsifiable, for example, claiming that the tooth fairy is real because you read about it in stories and your tooth was replaced with money overnight. This claim cannot be tested and proven wrong, therefore, it is not valid.
Key Feature of Science
When is the study game due?
FRIDAY (25th)
You want to test the relationship of attendance and students overall performance. The conclusion from these results only applies to the sample, and no causation can be stated. What kind of study is this?
Correlational/Observational Studies
What is known as the third Variable Problem, which influences or impacts both the independent variable and dependent variable? Due to this, there might be a correlation between the two variables that is not necessarily true.
Cofounding variables
Let’s say you ran an experiment on the amount of calories burned per minute spent running on a treadmill. If you had a group of individuals run on the treadmill each for 5, 10, and 15 minutes, you would most likely find that the more time spent running on a treadmill, more calories would be burned. Is this an example of correlation or causation?
Correlation
An Individual or group of individuals/items that are used by researchers to represent an entire population. If I wanted to know the average age in my neighborhood, I would record all ages of the people living in 5 houses out of 30 houses to represent the entire neighborhood. What is this called?
Sample
Stress
What variable is located on the x-axis?
Independent Variable
What concept do these features relate to? Fixed ideas, no peer review, selects only favorable discoveries, sees criticism as conspiracy, non-repeatable results, claims of widespread usefulness, and use of “ball-park” measurements.

What is Martin sons name?
Valentine
What is the term that is used when given the larger group that a sample is taken from?
Population
We have an entire student body grades 9-12 that is able to be chosen to take a survey on if they feel like they learn better online or in person. Anyone can be chosen out of the entire student body. What kind of sample is this?
Simple-Random Sample
9:05-9:55
What is an explicit representation where action “A” causes action “B”?
Causation
Some children in a class choose to play the viola and others choose to play the violin. You use these already chosen groups to evaluate their progress. What kind of study is this?
Quasi-experimental Design
When is the first quiz due?
Sunday the 27th
