Intro Spreadsheets
Term / Definition Unit 2
| Term | Definition |
|---|---|
| What type of data can spreadsheet cells hold? | Spreadsheet cells can hold numbers, dates, times, and text. |
| How do you perform calculations in Excel? | Start with the equals sign (=) to indicate that you want to perform a calculation. |
| What happens if you type "1+1" in a cell without the equals sign? | It will display the text "1+1" rather than calculating the result. |
| What are formulas in spreadsheets? | Formulas perform calculations based on expressions, which may include cell references and math operators. |
| What is a function in Excel? | A built-in tool to help perform more complex calculations. |
| Why are formulas important in spreadsheets? | They produce consistent results, automate tasks, and allow for reusable templates. |
| How do formulas produce consistent results? | They can be static (e.g., =1+1 always equals 2) or dynamic, updating automatically when referenced cells change. |
| What is the benefit of automating tasks with formulas? | It allows for repetitive calculations, such as averages, to be done automatically without recreating the formula each time. |
| What is a reusable template in Excel? | A template that can be reused with changing input data while keeping fixed calculations intact. |
| When using formulas, what do the copy and paste features do? | They allow you to reuse a formula from one cell to another. |
| What character signals to Excel that the contents of a cell should be treated as a calculation? | The equals sign (=). |
| What kind of function automatically updates when the values in the referenced cells change? | A dynamic function. |
| What is the purpose of a spreadsheet template? | It can be used repeatedly with changing inputs while keeping the calculations fixed. |
| What are the statistical functions? | SUM, COUNT, COUNTA, AVERAGE, MAX, and MIN. |
| How do you use the SUM function in Excel? | Type =SUM(A1:A7) to calculate the total of numbers in a range, like A1 through A7. |
| What does the COUNT function do in Excel? | It counts only the numeric cells in a given range. |
| How does the COUNTA function differ from the COUNT function? | COUNTA counts all non-blank cells, including both numbers and text. |
| What does the AVERAGE function do in Excel? | It calculates the mean of numbers in a given range, ignoring non-numeric data. |
| What does the MAX function return? | It returns the highest value in a specified range. |
| What does the MIN function return? | It returns the lowest value in a specified range. |
| What is the purpose of AutoSum in Excel? | AutoSum quickly inserts functions like SUM, AVERAGE, COUNT, MAX, and MIN for selected cells. |
| How does Excel store dates and times? | Excel stores dates as whole numbers and times as decimals. For example, 10/15/2022 at 7:37 AM is stored as 448490.31753. |
| How can you perform calculations with dates and times in Excel? | You can subtract dates to find the number of days between them, or subtract times to calculate the time difference. |
| How do you calculate elapsed time in minutes in Excel? | Multiply the decimal time difference by 24 (for hours) and then by 60 (for minutes). |
| What is the TODAY function in Excel? | The TODAY function inserts the current date into your worksheet and updates automatically whenever Excel recalculates. Example: =TODAY(). |
| What is the NOW function in Excel? | The NOW function displays the current date and time and updates automatically whenever Excel recalculates. Example: =NOW(). |
| What do the MONTH, DAY, and YEAR functions do in Excel? | These functions extract the specific parts of a date: MONTH: Extracts the month DAY: Extracts the day of the month YEAR: Extracts the year |
| What do the HOUR, MINUTE, and SECOND functions do in Excel? | They extract specific parts of a time: HOUR: Displays the hour MINUTE: Displays the minutes SECOND: Displays the seconds |
| What is the significance of the decimal part of an Excel date/time number? | The decimal part represents the time, with the whole number representing the date. |
| What is the purpose of the equals sign (=) in an Excel formula? | It signals that the cell should be treated as a formula. |
| What are the arithmetic operators used in Excel formulas? | Addition (+) Subtraction (–) Multiplication (*) Division (/) Exponents (^) |
| What is the standard order of operations in Excel when evaluating a formula? | Parentheses Exponents Multiplication and Division (left to right) Addition and Subtraction (left to right) |
| In the formula =2^3–8/4*2+7, what is the first step of evaluation? | Exponents: 2^3 = 8, so the formula becomes =8–8/4*2+7. |
| How would you evaluate =2^3–8/4*(2+7) step by step? | Parentheses: (2+7) = 9 → =2^3–8/4*9 Exponents: 2^3 = 8 → =8–8/4*9 Division and Multiplication (left to right): 8/4 = 2, then 2*9 = 18 → =8–18 Subtraction: 8–18 = -10. |
| How do parentheses affect the order of operations in Excel? | Parentheses change the order of operations, ensuring that calculations within parentheses are done first. |
| In the formula =(C6+2*C8)*(1+C3), what happens when you remove the parentheses? | The final price without parentheses is $413.56, but with parentheses, the final price after tax is $441.40. |
| What is the result of the formula =(C6+2*C8)*(1-C2)*(1+C3) when both items are on sale? | The final price after tax is $308.98. |
| How does the formula =(C6*(1-C2)+2*C8)*(1+C3) calculate the price when the pool is on sale but chlorine is at full price? | The final price after tax is $329.00. |
| What happens if you remove the parentheses from the formula =(C6*(1-C2)+2*C8)*(1+C3)? | Without parentheses, the final price is $413.26. |
| What is the purpose of formula auditing in Excel? | Formula auditing helps identify and correct mistakes in formulas, ensuring that spreadsheet calculations are accurate. |
| What tool in Excel allows you to display formulas instead of calculated results? | The "Show Formulas" feature in the Formula Auditing group displays all formulas in the worksheet instead of the results. |
| How do you activate the "Show Formulas" tool in Excel? | Go to the Formulas ribbon and click "Show Formulas" in the Formula Auditing group to display all formulas. |
| What is the benefit of using the "Show Formulas" tool in troubleshooting? | It allows you to view the formulas themselves, making it easier to check for errors and ensure the correct formula structure. |
| What is the difference between Trace Precedents and Trace Dependents in formula auditing? | Trace Precedents shows which cells are referenced by the selected formula. Trace Dependents shows which cells depend on the selected formula. |
| Are the Trace Precedents and Trace Dependents features available in the online version of Excel? | No, these features are not available in the online version of Excel. You need to switch to the desktop version to use them. |
| How can you switch to the desktop version of Excel to access formula auditing tools? | Click "Advanced Options" in the right menu, select the version of Excel you want to use, and click "Save" to switch to the desktop version. |
| Why is formula auditing important when working with complex formulas in Excel? | Formula auditing helps track down errors in complex formulas, ensuring accurate calculations by reviewing and correcting the formula structure. |
| What is an example of a formula that might be audited in a spreadsheet? | A formula calculating sales tax, where the sales amount is multiplied by the tax rate using an absolute reference, can be audited for correctness. |
| What happens when you use the "Show Formulas" tool in Excel? | It displays all formulas in the worksheet, making it easier to check the formula syntax and identify any potential errors. |
