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.
What is a correlation variable?
Any variable can be a correlation variable. In some cases there may be no apparent correlation but that, in itself, that means nothing. For example, the x and y coordinates in the equation of a circle (or any symmetric shape) are not correlated. On the other hand, there is a pretty good correlation between my age and the number of cars in the world.A correlation variable is simply a variable that you study to see if changes in the variable that you are interested in is, in any way, related to changes in the correlation variable, and to get some idea of the degree to which they move in line.
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 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
