### Grade 6 ICT Revision Guide - Excel Basic Functions
#### Key Topics to Review:
1. How to use the SUM() function to add numbers.
2. How to use the AVERAGE() function to calculate the mean.
3. How to use the MAX() and MIN() functions.
4. How to use the COUNT() function to count numerical entries.
5. How to use AutoSum to quickly calculate values.
#### Practice Questions with Examples:
1. **What does the SUM() function do in Excel?**
- **Example Answer:** The SUM() function adds all the numbers in a selected range of cells.
- Example: `=SUM(A1:A5)` adds all values from A1 to A5.
2. **How do you find the highest value in a list of numbers?**
- **Example:** Use the MAX() function.
- Example: `=MAX(B1:B10)` returns the highest number in the range B1 to B10.
3. **What is the difference between COUNT() and AVERAGE()?**
- **Example Answer:**
- COUNT() counts the number of numeric entries in a range.
- AVERAGE() calculates the mean of a set of numbers.
- Example: `=COUNT(A1:A10)` counts the numeric values in A1 to A10,
while `=AVERAGE(A1:A10)` finds the average of those values.
4. **Write an Excel formula to find the average of cells A1 to A10.**
- **Example:** `=AVERAGE(A1:A10)`
5. **How would you use AutoSum to quickly sum up a column of numbers?**
- **Example:**
- Click on the cell where you want the total.
- Press the AutoSum button (AutoSum) on the Home tab.
- Excel will automatically select a range, and pressing Enter will apply the SUM formula.
#### Additional Practice:
1. Try using SUM(), AVERAGE(), MAX(), MIN(), and COUNT() on different sets of numbers.
2. Experiment with AutoSum on a new column of numbers.
3. Find the smallest number in a list using the MIN() function.
4. Count how many numbers are in a range using COUNT().
5. Save your work and verify your calculations by using a calculator to check your formulas.
