What variable in a study or experiment is the variable changed by the experimenter

What refers to a statistical relationship between two or more variables where changes in one variable are associated with changes in another variable. These can range between -1 and 1. A value of 0 or close to 0 means there is no (linear) relationship. A value close to 1 means that there is a strong positive relationship. A value close to -1 means that there is a strong negative relationship. 

What is the relationship between the cause and the effect 

True or False: A simple random sample is a type of sample that gives every member of the population an equal opportunity to be part of the sample

An entire group of individuals that may be included in a sample for a study. 

a smaller group of individuals from the same population

What are the 3 key features of science?

What variable is this scenario? 

A researcher could be conducting a study about how well plants grow in a multitude of different environments. The researcher would randomly choose 1 type of plant and plant multiple of them in the same soil, watering it the same amount and using the same pot, but placing them in different locations. 

What is this called?

A researcher is looking at the relationship between time spent studying for a chemistry exam and grade on the chemistry exam. A simple random sample of students would be divided into four groups, each studying for different amounts of time and then asked to take a chemistry exam in a controlled environment.

What is this study design called? Researchers want to observe how different methods of teaching work for high school students. Since high school students already have assigned classes and times for each class, it would not make sense to separate them. Because of this, each teacher of a certain subject would be instructed to teach in a different way than others to test how well the predetermined methods work.

Interviews, observations, focus groups, experiments, and secondary data analysis are all forms of data collection. A different form of data collection utilizes questionnaires, interviews, or online forms. Which type of data collection is this?

If a study where each student's name is put into a hat, and a certain number of names are drawn without replacement is a form of simple random sampling, then what form of sampling is being used in a study on household income where the population is divided into income brackets (e.g., low-income, middle-income, high-income), and samples are randomly selected from each bracket to ensure representation from all income levels?

What variable undermines the validity of the study and acts as a third variable that will affect the dependent variable?
