Sciences
This type of science does not include these features - willingness to change, peer review, and verifiable results.
Pseudoscience (Connect/Compare)
This variable is manipulated by researchers in an experimental study to study its effects.
Independent Variable (Define)
A group of researchers want to eliminate any possible bias or differences between groups when conducting an experiment. What is the best type of experimental design for this?
Randomized Controlled Trial (RCT)/Experimental studies (Connect/Compare)
This concept is where two variables are related to each other, positive or negative. This is an example of...
Correlation (Define)
What is the name of the group of things we want information about?
Population (Define)
The features of this science include being willing to change with new evidence, taking account of all new discoveries, inviting criticism, and accurate measurements.
Science (Define)
In an experiment, researchers are studying to see if the number of cups of coffee office workers drink affects their productivity. In this experiment, the office workers’ productivity level is what variable?
Dependent Variable (Connect/Compare)
A group of researchers want to study the effects of two new drugs on the body. They split the population into two groups. One group will receive drug 1, and the other group will receive drug 2. What is the name of this type of experiment?
Quasi Experimental Design (Connect/Compare)
This variable directly leads to or influences a change in another variable.
Causation (Define)
Researchers take people from the population to study them and draw conclusions about in an experiment. What is this concept?
Sample (Define)
There is a group of scientists who are working on a theory to prove that aliens don’t exist. They refuse to look at any proof of aliens existing, their measurements are inaccurate, and they see criticism as conspiracy. What is the term that describes this?
Pseudoscience (Connect/Compare)
In an experiment, researchers test how the level of exercise affects weight loss in Ibs. However they don’t account for diet, which is an important factor. Therefore the researchers won’t be able to effectively test the effects of exercise on weight loss. This is an example of what type of variable?
Confounding Variable (Connect/Compare)
A group of researchers want to study the effects of depression. Unfortunately, it is unethical to make participants feel depressed in order to study them. Additionally, depression is hard to study due to multiple outside factors. What is the name of a type of experimental design the researchers can use to get around this?
Survey (Connect/Compare)
In the summertime, sales of sunscreen and ice cream increase at the same time. Is this an example of correlation or causation?
Correlation (Define)
There are two experiments being conducted. In the first experiment, researchers pick randomly from the population to be studied. In the second experiment, researchers first split participants into groups of similar characteristics, and then study them. What are the names of these two types of sampling?
Simple random sampling and stratified random sampling (Connect/Compare)
