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 is a Correlation coefficient of 0.00457?
Evidence that there is no correlation.
What are the trends of a line?
They can be positive correlation, negative correlation or no correlation depending on 'line of best fit'
Is -0.0001 a correlation coefficient?
Yes it can be a correlation coefficient.
Is 1.5 a correlation coefficient?
No, it cannot be a correlation coefficient.
Explain how lipid hydrolysis can be correlated with the pathogenicity of a bacterium?
A very loose correlation can be made between breaking down gelatin and the ability to breakdown tissue. The scientific process can only be replicated within a lap environment but with the constant evolution of bacterium it is possible at some point for the gelatin and tissue correlation to be much stronger.
Auto correlation and cross correlation?
Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
What are three types of correlations?
positive correlation-negative correlation and no correlation
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
What is the maximum and minimum value of the correlation coefficient?
The correlation can be anything between +1 (strong positive correlation), passing through zero (no correlation), to -1 (strong negative correlation).
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.
Are negative correlation and reverse correlation same?
No.
What rhymes with correlation?
Indentation rhymes with correlation
What is a Correlation coefficient of 0.00457?
Evidence that there is no correlation.
Is 1.10 a strong correlation?
No, The correlation can not be over 1. An example of a strong correlation would be .99
Does the units affect the correlation?
No. The units of the two variables in a correlation will not change the value of the correlation coefficient.
What is a correlation coefficient?
a number derived from the formula for measuring a correlation and indicating the strength and direction of a correlation
