**How To Calculate**

- Step 1: Find the mean of x, and the mean of y.
- Step 2: Subtract the mean of x from every x value (call them "a"), and subtract the mean of y from every y value (call them "b")
- Step 3: Calculate: ab, a
^{2}and b^{2}for every value. - Step 4: Sum up ab, sum up a
^{2}and sum up b.

Given a bivariate quantitative dataset the least square regression line, almost always abbreviated to LSRL, is **the line for which the sum of the squares of the residuals is the smallest possible**.

In Excel to find the correlation coefficient use the formula : **=CORREL(array1,array2)** array1 : array of variable x array2: array of variable y To insert array1 and array2 just select the cell range for both.

There are three basic types of correlation: positive correlation: the two variables change in the same direction. negative correlation: the two variables change in opposite directions. no correlation: there is no association or relevant relationship between the two variables.

**Here are the steps to take in calculating the correlation coefficient:**

- Determine your data sets.
- Calculate the standardized value for your x variables.
- Calculate the standardized value for your y variables.
- Multiply and find the sum.
- Divide the sum and determine the correlation coefficient.

**Different methods of finding correlation**

- a) Karl Pearson's coefficient method.
- b) Rank method / Spearman's coefficient method.
- c) Scatter Diagram.

There are **two main types of correlation coefficients**: Pearson's product moment correlation coefficient and Spearman's rank correlation coefficient. The correct usage of correlation coefficient type depends on the types of variables being studied.

**There are three types of correlation:**

- Positive and negative correlation.
- Linear and non-linear correlation.
- Simple, multiple, and partial correlation.

Because values influence individual behaviour, **negative behaviour is also the result of negative values**. Mitchell and Scott (1990) stated that increase in unethical business practices are usually attributed to change of values. This should show how important and relevant values are to an organisation.

A reserve is **a portion of a resource that occurs naturally in or on the Earth's crust that can be extracted for profit**. Define the term ore.

Scientists believe that **there are more than three billion base pairs of DNA in human genes and more than 25,000 genes in the human genome**, according to an article in Nature. An entire copy of that genome exists in each of the 30 to 40 trillion cells in the human body.

Blower is equipment or a device which increases the velocity of air or gas when it is passed through equipped impellers. They are mainly used for **flow of air/gas required for exhausting, aspirating, cooling, ventilating, conveying etc**. Blower is also commonly known as Centrifugal Fans in industry.

**Enantiomers and diastereomers are the only two stereochemical relationships that you can have between any two molecules**. The stereoisomers are any two molecules that fulfill the following two requirements: Both molecules must have the same molecular formula, and. Both molecules must have the same atom connectivity.

The consensus seems to be about **14 hours a week, or two hours a day**. This is in line with a common study-time recommendation that you spend two hours studying for each hour in class (3 hours of lecture plus 4 of lab = 14 hours of work outside of class).

The definition of an industry is **any large-scale business activity or a type of productive manufacture or trade**. An example of industry is the coal mining business. noun.

To outsiders, the odds are **1 in 20 that a correlation (in this case a genetic association) will be observed if there is in fact no association** (assuming that a scientific journal accepts a P threshold of 0.05 as sufficient evidence for publication) and 1 in 400 that the discovery will be replicated by chance, providing
