What distinguishes the correlation method from experimental?
The correlation method examines the relationship between two or more variables to determine if they move together, without implying a cause-and-effect relationship. In contrast, experimental methods involve the manipulation of one variable to observe its effect on another, allowing researchers to establish causality. While correlation can reveal patterns or associations, only experiments can determine whether changes in one variable directly lead to changes in another. Thus, the key distinction lies in the ability of experimental methods to infer causation, which correlation methods cannot provide.
Can correlation alone prove causation?
No, correlation alone cannot prove causation. While a correlation between two variables indicates that they may be related, it does not demonstrate that one variable causes the other. Other factors, such as confounding variables or coincidence, can also explain the observed correlation. Establishing causation typically requires further evidence, such as experimental data or longitudinal studies.
What is a correlation control study?
A correlation control study is a research design that examines the relationship between two or more variables to determine if they are associated or correlated. Unlike experimental studies, it does not manipulate variables but instead observes them in their natural settings. This type of study helps identify patterns and potential relationships, but it cannot establish causation. Researchers often use statistical methods to analyze the strength and direction of the correlations found.
What is a sample correlation?
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
What is a Correlation coefficient of 0.00457?
Evidence that there is no correlation.

The group of experimental subjects which is left natural or left unchanged is called the?
experimental group
Auto correlation and cross correlation?
Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
How are observational studies of populations different from experimental studies?
Observational studies observe natural phenomena without intervention, while experimental studies manipulate variables to determine cause and effect. Observational studies are useful for understanding associations, while experimental studies can establish causal relationships between variables. Experimental studies involve random assignment of participants to groups, while observational studies rely on natural groupings.
What are three types of correlations?
positive correlation-negative correlation and no correlation
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).

What is the maximum and minimum value of the correlation coefficient?
The correlation can be anything between +1 (strong positive correlation), passing through zero (no correlation), to -1 (strong negative correlation).
What is a sample correlation?
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
