# What is weak correlation?

R less than 0.3

### Can you provide an example of a weak positive correlation?

You can find examples by typing it in to Google. Weak positive correlation is a set of points on a graph that are loosely set around the line of best fit. The line will be positive rising up from left to right. A weak correlation can vary a lot as long as you can decipher which direction the data tends towards you have a correlation. If the points are close to the line of best…

### What is a weak negative correlation?

A negative correlation is when you compare 2 sets of data on a line graph (e.g. scores in a French test and scores in an English test), the higher one thing is, the lower the other is (e.g. someone might score 98% on the French test but only 12% on the English test (or visa versa)). A positive correlation is the other way around. A weak correlation is when there is a lot of deviation…

### How do you find out what correlation a scatter plot has?

It is easy to find the correlation. First you see how far apart the dots are. if they are going UP like this / <---- it means its a positive correlation. if its like this \ <---- its a negative correlation. if its everywhere its a neutral (although they almost never do them in tests). To find out the strength is your opinion. If alot are grouped together almost making a line its a Strong…

### Is r0.45 a strong correlation?

No, it's a small enough value that it doesn't suggest any correlation at all. There's no hard-and-fast rule for interpreting the correlation coefficient: a very strong correlation in one discipline might be considered weak in others, and the correlation coefficient might be misleading in some cases. But most of the time, you want r to be at least plus or minus 0.9 before even thinking about any relation between the data.

### Would a 0.5 correlation be considered weak modest strong or very weak?

It really depends a lot on the context. The Cohen scale, for example, puts a correlation of 0.5 right on the cusp of "medium/modest" (0.30-0.49) and "large/strong" (0.50-1.00). However these cutoff criteria are largely arbitrary and shouldn't be applied too strictly. A correlation of 0.5 might be regarded as strong in some social science situations (e.g. where the measures are based on 5-point Likert scales) or weak in physical science situations where instrumentation can be…

### What is correlation What are the different types of correlation Why is it important to determine correlation What does it mean when it is said that two variables have no correlation?

A correlation is the relationship between two or more variables. Correlations are described as either weak or strong, and positive or negative. There can be a perfect correlation between variables, or no correlation between variables. It is important to determine the correlation between variables in order to know if and how closely changes in one variable are reflected by changes in another variable. This is done by determining the coefficient of correlation (r), which describes…
