Veterinary devices. Correlation and dependence. In statistics, dependence is any statistical relationship between two random variables or two sets of data.
Correlation refers to any of a broad class of statistical relationships involving dependence. Familiar examples of dependent phenomena include the correlation between the physical statures of parents and their offspring, and the correlation between the demand for a product and its price. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather.
In this example there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling; however, statistical dependence is not sufficient to demonstrate the presence of such a causal relationship (i.e., correlation does not imply causation). Pearson's product-moment coefficient[edit] Correlation. When two sets of data are strongly linked together we say they have a High Correlation.
The word Correlation is made of Co- (meaning "together"), and Relation Correlation is Positive when the values increase together, and Correlation is Negative when one value decreases as the other increases Like this: Correlation can have a value: 1 is a perfect positive correlation 0 is no correlation (the values don't seem linked at all) -1 is a perfect negative correlation The value shows how good the correlation is (not how steep the line is), and if it is positive or negative.
Example: Ice Cream Sales The local ice cream shop keeps track of how much ice cream they sell versus the temperature on that day, here are their figures for the last 12 days: And here is the same data as a Scatter Plot: We can easily see that warmer weather leads to more sales, the relationship is good but not perfect. In fact the correlation is 0.9575 ... see at the end how I calculated it.
COEFFICIENT.CORRELATION. Calculating Growth Rates. 1.
Calculating Percent (Straight-Line) Growth Rates The percent change from one period to another is calculated from the formula: Where: PR = Percent Rate VPresent = Present or Future Value VPast = Past or Present Value The annual percentage growth rate is simply the percent growth divided by N, the number of years. VPresent = 280,000 VPast = 250,000 N = 10 Years The population of Lane County grew 12 percent between 1980 and 1990 or at an rate of 1.2 percent annually. 2. Another common method of calculating rates of change is the Average Annual or Compound Growth Rate (AAGR). This can also be written algebraically as: (((((100 * (1.05) * 1.05) * 1.05) * 1.05) * 1.05) A.
