How do you define strengths and weaknesses?
Strengths and weaknesses generally refer to a person’s character. Often a strength can be a weakness, and vice versa, a weakness can be a strength.
What are two major limitations for a correlation?
Limitations of Correlations Correlation is not and cannot be taken to imply causation. Even if there is a very strong association between two variables we cannot assume that one causes the other. For example suppose we found a positive correlation between watching violence on T.V. and violent behavior in adolescence.
Why is correlation important?
A correlation between variables indicates that as one variable changes in value, the other variable tends to change in a specific direction. Understanding that relationship is useful because we can use the value of one variable to predict the value of the other variable.
What does a correlation of 0 mean?
A value of zero indicates that there is no relationship between the two variables. If the correlation coefficient of two variables is zero, it signifies that there is no linear relationship between the variables.
Can a weak correlation be significant?
Do not confuse statistical significance with practical importance. However, a weak correlation can be statistically significant, if the sample size is large enough.
