What is The primary purpose of correlational research is to explore relationships and among variables. causation predictions randomization controls?
The primary purpose of correlational research is to explore relationships among variables to understand how they are related. It does not determine causation, make predictions, involve randomization, or have control groups.
What are the types of randomization?
The common types of randomization include simple randomization, block randomization, and stratified randomization. Simple randomization involves assigning participants randomly to treatment groups with each having an equal chance of being selected. Block randomization involves grouping participants into blocks and then randomly assigning them to treatment groups within each block. Stratified randomization involves dividing participants into distinct subgroups based on specific criteria and then randomizing within each subgroup.
How can a scientist reduce bias in a scientific investigation?
To reduce bias in a scientific investigation, a scientist can use randomization in sampling, blind studies, and double-blind studies. Randomization helps to minimize selection bias, while blind studies prevent participants from knowing which group they are in, reducing response bias. In double-blind studies, both the participants and the researchers are unaware of who is receiving the treatment, further minimizing bias.
What are the 4 principles essentials to properly designed experimental studies?
. Randomization.... eliminate bias . Replication . Blocking ( Local control).... reduces variability
What is epidemology?

Who studies illness and its treatment?
The name of the profession that studies illnesses and their treatments is epidemiology. They study patterns, causes, and effects of all types of health conditions and diseases.
What steps can be taken to minimize potential bias in research studies?
To minimize potential bias in research studies, researchers can use randomization, blinding techniques, and transparent reporting of methods and results. Randomization helps ensure that participants are assigned to groups without bias, blinding techniques prevent researchers and participants from knowing which group they are in, and transparent reporting allows others to assess the study's validity.
Is randomization a word?
Yes.
