Standard Deviation
Standard deviation describes how variable, or how spread out, the scores are in a distribution. A small standard deviation indicates that the scores are typically close to the mean, a large standard deviation indicates that the scores are generally far from the mean.

6. HLOOKUP APPLIED UNIQUELY
Application: In our grade sheet we are using HLOOKUP to calculate grades based on the Overall Numerical Score in M10, and assigning the students letter grades.
Applied Uniquely: You may apply HLOOKUP uniquely by calculating grades for one of the assignments—therefore using D10,F10 etc. instead of M10. Or, you can assign comments to the students instead of letter grades by using a table with comments in place of letter grades, and you can continue to use the Overall Numerical Score in M10

8. Excel Error Messages in Formulas
N/A#! – This error occurs when a value is not available to a function or a formula.
#REF! – This error occurs when a cell reference is not valid. It can occur when one of the cells referenced in the formula has been deleted.
#DIV/0! – This error occurs when a number is divided by zero, that is when a fraction’s denominator evaluates to zero.
#VALUE! – This error indicates that you are trying to do math with non-numeric data.

9. Relative vs. Absolute Reference
A relative reference is a cell reference that changes when it is copied and pasted in a new location.
An absolute reference is a cell reference that doesn’t change when it is copied. Excel does not adjust the cell reference because the cell reference points to a fixed, or absolute, location in the worksheet, and it remains fixed when the copied formula is pasted. In Excel, an absolute reference appears with a dollar sign ($) before each column and row designation. For example, $B$8 is an absolute reference, and when it is used in a formula, Excel will always point to the cell located at the intersection of column B and row 8.
