Do you feel that being proficient in Microsoft Excel or Google Sheets is almost a basic life skill in today's data-driven world? The long-standing presence and widespread use of Excel across various industries certainly suggest it's here to stay.

Why remain intimidated by this powerful tool? Our approach is straightforward in this complete guide: we start with the most basic functions and gradually increase in complexity, following a structured lesson plan, just like your teacher in college. Let's explore and simplify Excel together!

1. SUM 

Have you ever needed a quick way to add up figures, like sales or expenses? Excel's SUM function seems basic, yet it can save you hours of work. It's simple and efficient, perfect for summing up numbers in a range of cells.

How to use SUM:

1. The basic structure of the SUM function is =SUM(number1, [number2], ...).

Example: Imagine you have monthly sales figures in cells A1 to A6. To find the total sales, you'd use =SUM(A1:A6). This formula adds the values in cells A1 through A6.

Common error with SUM:

At times, you may accidentally leave out a cell or a range of cells in your SUM formula. So, it can lead to incorrect totals.

2. AVERAGE

Once you're familiar with SUM, the AVERAGE function is your next step. It's pivotal for calculating the mean, which gives you a snapshot of the typical or central value in your data set. As a small business owner, this is invaluable for assessing things like average sales, expenses, or customer ratings.

How to use AVERAGE:

1. The basic structure of the AVERAGE function is AVERAGE(number1, [number2], ...).

Example: Let's say you have weekly sales figures in cells A1 to A6. To find the average weekly sales, you'd use =AVERAGE(A1:A6). 

Common error with AVERAGE:

AVERAGE gets confused if there are text or blank cells in your range.

3. MAX and MIN

Why are MAX and MIN useful for you? They will pinpointing the highest and lowest values in your data set. You can use them to identifying extremes, like the peak and trough of sales, maximum costs, or minimum scores in a more visual way.

How to use MAX and MIN:

1. MAX: The structure is MAX(number1, [number2], ...).
2. MIN: The structure is MIN(number1, [number2], ...).

Examples: Max: To find the highest sales figure in cells A1 to A6, use =MAX(A1:A6). 

Min: To find the lowest temperature recorded in cells A1 to A6, use =MIN(A1:A6).

Common error with MAX and MIN:

Sometimes, the range might not include all the cells you intended to analyze.

4. COUNT & COUNTA

Moving forward, let's explore the COUNT and COUNTA functions. COUNT is used to count the number of cells in a range that contain numbers, and COUNTA counts the number of non-empty cells. These functions are essential for understanding the volume of data, like how many entries you have in a list or how many cells contain numerical values.

How to use COUNT and COUNTA:

1. COUNT: COUNT(value1, [value2], ...)
   • value1, value2, ...: These are the cells or range you want to count. Only cells with numbers are counted.
2. COUNTA: COUNTA(value1, [value2], ...)
   • This function counts all non-empty cells, including those with text, numbers, or dates.

Examples: If you have a list of sales figures in cells A1 to A6 and want to know how many of these cells actually have sales data (numbers), use =COUNT(A1:A6).

To count how many cells in a range F1 to F20 are not empty (including text, dates, etc.), use =COUNTA(F1:F20).

Common error with COUNT and COUNTA:

Using COUNT when you should use COUNTA, or vice versa, leads to incorrect counts.

5. IF

The next step is learning the IF function. Versatile and can be used in various scenarios, like determining if sales targets are met, categorizing expenses, or automating decision-making processes in your data.

How to use IF:

1. The basic structure of the IF function is IF(logical_test, value_if_true, value_if_false).
2. logical_test: This is a condition that can be either TRUE or FALSE.
3. value_if_true: The value that is returned if the condition is TRUE.
4. value_if_false: The value that is returned if the condition is FALSE.

Example: Imagine you're tracking monthly sales in cell A1 and have a target of $500. To find out whether the target is met, you'd use =IF(A1 >= 500, "Target Met", "Target Not Met"). This formula checks if the sales in A1 are greater than or equal to $500. If yes, it returns "Target Met"; otherwise, it returns "Target Not Met".

Common error with IF:

Sometimes the logical test might not be set up correctly, leading to unexpected results.
