What are Advantages to Correlation study?
An advantage of using a correlational study is that it allows you to investigate variables that cannot be directly manipulated.
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.
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 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 are Disadvantages to Correlation study?
Correlation study is restricted to linear relationships between the variable(s) being studied.
A relationship between two or more variables that is shown in an observational study is a?
Correlation-apex (;
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?
d correlation study
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 science cant not study?
nature
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.

What is clinical correlation of vascular congestion?
Clinical correlation of vascular congestion means that a buildup in the vessels was seen on the diagnostic imaging study, and the radiologist interpreting the study wants your health care provider to see if that has anything to do with your symptoms, since only s/he has the benefit of your full history and exam.
