What is the acceptable range of correlation coefficient?
The correlation coefficient, typically denoted as "r," ranges from -1 to +1. A value of +1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation. Generally, values between 0.1 and 0.3 suggest a weak correlation, 0.3 to 0.5 indicate a moderate correlation, and above 0.5 show a strong correlation. The interpretation may vary depending on the context and the specific fields of study.
What are the advantages and disadvantages of data collection methods in statistics?
There are both advantages and disadvantages of data collection methods in statistics. The main advantages are the metrics and correlation one can draw from statistics. The disadvantages stem from sampling errors.
What are the advantages of regression over correlation?
Correlation is a measure of association between two variables and the variables are not designated as dependent or independent. Simple regression is used to examine the relationship between one dependent and one independent variable. It goes beyond correlation by adding prediction capabilities.
Is there negative correlation between weight and distance walked on an average day?
That's a question that can only really be answered via a study. Take a random sample of people (from your school for example) and plot their weight against their average daily walking distance (you may have to make your subjects carry a pedometer during the study period). Do you see a negative relationship on the graph?As a second step, calculate the correlation coefficient. As negative correlation gets stronger the correlation coefficient will get closer to -1.
Which hypothesis is best examined with a correlation analysis?
A hypothesis best examined with a correlation analysis typically involves the relationship between two continuous variables. For example, a hypothesis stating that "increased study time is associated with higher test scores" can be effectively tested using correlation analysis to determine the strength and direction of the relationship between study time and test scores. Correlation analysis helps identify whether changes in one variable correspond to changes in another, but it does not imply causation.
What are Disadvantages to Correlation study?
Correlation study is restricted to linear relationships between the variable(s) being studied.

What are the disadvantages of a correlation study?
Causation cannot be determined.
Which study is best for examining the lifespan of twins who grew up apart?

Correlational study is it cause and effect?
No correlational study is not cause and effect because correlation does not measure cause.
In psychology what is a correlational study used to determine?
A correlation study is one that determines the pattern between two objects or ideas. The study between alcohol consumption and passing college grades is a correlation study for example.

What are the advantages and disadvantages of correlation method?
The advantage of the correlational research method is the ability to prove a positive or negative correlation between two subjects . The disadvantage of this is the unclear interpreation of cause and affect. moletsane

What is it call when grades go up as the number of study hours go up?
You might be referring to a positive correlation between grades and number of study hours.
