In simple terms, the Pearson Correlation answers the question: Can the data be represented on a line?

### Regression and correlation analysis in Excel: instruction executio

• As much as the correlation coefficient is closer to +1 or -1, it indicates positive (+1) or negative (-1) correlation between the arrays. Positive correlation means that if the values in one array are increasing, the values in the other array increase as well. A correlation coefficient that is closer to 0, indicates no or weak correlation.
• In this example we are taking a perfect positive correlation, for example, considering a variable X value increases with the value of variable and value of variable X decreases with the value of variable Y decreases as shown in the below table.
• § Many research projects are correlational studies because they investigate the relationships that may exist between variables. Prior to investigating the relationship between two quantitative variables, it is always helpful to create a graphical representation that includes both of these variables
• In the first OFFSET function, ROWS(\$1:1) has transformed to ROWS(\$1:3) because the second coordinate is relative, so it changes based on the relative position of the row where the formula is copied (2 rows down). Thus, ROWS() returns 3, from which we subtract 1, and get a range that is 2 columns to the right of the source range, i.e. \$D\$2:\$D\$13 (heater sales).
