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 a scatter diagram how is it useful?

Sometimes when we graph the relationship between two varying quantities of real life on a coordinate plane we get dots scattered on coordinate plane. For example graph average math score of students from grade 8. Let's consider their 8-week score. (1, 50) (2, 52), (3, 49), (4, 58), (5, 60), (6, 65), (7, 64), (8, 68). If you plot these coordinates you will get the points scattered points. 1) It is helpful to study the relationship between two varying quantities. 2) It says whether the relation is positive or negative. Sometimes we may not have any relation. 3) Such relation is called as correlation. 4) In the above example the graph has positive correlation. As the week increases the average scores also increases. There may be some down fall. Overall, it is a positive variation.


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.
