What does the term correlation analysis mean?
Correlation analysis is the relationship of two values. When two items are similar, they will have a high correlation. Should they differ, they will be much lower in variables.
What does a correlation coefficient indicate?
A correlation coefficient quantifies the strength and direction of the relationship between two variables. Ranging from -1 to 1, a value of 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 signifies no correlation. Higher absolute values indicate stronger relationships, while lower values suggest weaker or no relationships. It's important to note that correlation does not imply causation.
What correllation is discovered when higher scores on one variable is associated with lower scores on another variable?
A 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.
Is there a negative correlation between risk and the return the investor demand?
Yes, there is typically a negative correlation between risk and the return that investors demand. Generally, investors expect higher returns as compensation for taking on greater risk; conversely, lower-risk investments usually offer lower expected returns. This relationship is foundational in finance, illustrating the trade-off between risk and reward in investment decisions. However, individual preferences and market conditions can influence this correlation.

An observation that the higher the air temperature the lower the activity of test animals would be an example of what kind of correlation?
This would be an example of a negative correlation, where as one variable (air temperature) increases, the other variable (activity of test animals) decreases.
What correllation is discovered when higher scores on one variable is associated with lower scores on another variable?
A negative correlation
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 is a Q correlation?
1. For each pair of variables, calculate the q-correlation, using the formula: , where 1. For each pair of variables, calculate the q-correlation, using the formula: , where = number of data points in the upper-right quadrant = number of data points in the lower-left quadrant = number of data points in the lower-right quadrant = number of data points in the upper-left quadrant n = n1 + n2 + n3 + n4
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 exist if the y-coordinated decrease as the x-coordinates increase?
You have a negative correlation, or a line, getting lower as it goes further to the right.
What is the correlation between gauge and millimeter size in beading wire - I'm referring to beading wire here not electrical wire?
The general correlation is the lower the gauge number, the heavier the wire diameter gets. For specifics, see related link.
