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.
The goal of the scientist is to design an experiment that will be able to distinguish the difference between?
Correlation and causation.
What is a major way in which the psychologist's goal of explanation differs from the psychologist's goal of description?
The psychologist's goal of explanation involves understanding the underlying causes or reasons for behavior, while the goal of description involves simply observing and detailing behavior without delving into the reasons behind it. Explanation seeks to answer "why" a behavior occurs, while description focuses on "what" is observed.
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.
