• IF function displays one of two possible values depending on the outcome of a logical test
• Logical Test compares two things
• If the Logical Test equates to TRUE, the cell is filled with the True Value.
• If the Logical Test equates to FALSE, the cell is filled with the False Value.
IF Function
MAC: Logical Test is broken into 3 separate boxes
Use the IF function to assign the label of easy or hard based on the hours. If a course requires more than 3 hours of study time per week, we will label it HARD. Three or less hours of study is labeled EASY.
Course Difficulty Example
•What cell is used for the logical test?•What is the logical test?•What is the true value? False value?
Course Difficulty Example
3
Bonus Points Example
1. Open One Semester.xlsx2. Extra Credit
A. Add a new column to display the extra credit points. B. Give all students in the 8:00 Section 10 points of extra
credit. Students in the 9:00 section receive zero extra credit. (Display either 0 or 10 in this new column.)
3. Curve A. Add a new column to display the curved Exam 1 grades.B. Curve Exam 1 grades by increasing all Freshmen grades
by 10% and leaving all other grades the same. Show both the original and curved exam grades in separate columns. Do not show the curve points separately.
Shipping Cost Example• Open SmartPen Sales.xlsx.
• Delete the data in the Shipping Cost column.
• Use an IF statement to display 4.95 when the shipping method is standard and 14.95 if it is not standard.
SUMIF, COUNTIF & AVERAGEIF• SUMIF function includes a value in the
calculation only when the criteria is true
=sumif(range, criteria, sum_range)
• Each cell in range is compared to criteria.
• If that comparison equates to TRUE, the corresponding cell in sum_range is included in the calculation.
SUMIFS, COUNTIFS & AVERAGEIFS• SUMIFS function includes a value in the calculation
only when two or more criteria are true
=sumif(sum_range, criteria_range1, criteria1criteria_range2, criteria2)
• Each cell in rangex is compared to criteriax.
• If all comparisons equate to TRUE for a single row, the corresponding cell in sum_range is included in the calculation.
Grouping Worksheets• Hold SHIFT or CONTROL as you select sheet
tabs. Right-click and select Group.
• Allows you to make changes to multiple worksheets at once.
• All groups sheets must have same layout.
• Right-click, Ungroup
Income Statement ExampleOpen Income Statement.xlsx
1. Group all 12 months and apply:• Formatting for Clarity• Add Total Expenses
Calculation• Add Net Income Calculation
2. Ungroup Worksheets
Quarterly SmartPen Example
Open SmartPen Sales Qtr.xlsx.
This workbook has two more months of data added.
Quarterly SmartPen Sales Example
1. Group July, August and September worksheets:• Insert a new row just below Row 1.• Format this row as a calculation row.• Add SUM functions to the second row for
columns E and I – L. Assume we may be adding more invoices to all three worksheets so sum the current rows plus another hundred empty rows.
2. Ungroup the worksheets.• Change the quantity of the first July invoice to 27
and the first August invoice to 38.
3-D Cell References• Range on another sheet
Sheet1!A1:A10
• Range across multiple sheetsSheet1:Sheet3!A1
Quarterly Income Statement
Combine the Jan, Feb and Mar Income Statements into one quarterly worksheet.
Quarterly Income Statement1. Create 1st Quarter worksheet:• Copy a monthly worksheet• Rename sheet 1st Qtr• Delete amounts• Add January, February, March columns
2. Enter function to display amounts from monthly sheets • Start function with equal sign• Point to January Revenue cell• Press ENTER• Copy to expense amount cells• Repeat for each month
Annual Income StatementCreate a new worksheet that displays the total, January through December, of each figure.
Annual Income Statement1. Create Annual worksheet:• Copy a monthly worksheet• Rename sheet Annual• Delete amounts
2. Enter a function to total revenue• Start function with =SUM(• Point to January cell• Enter colon• Point to December cell• Press ENTER• Repeat for each amount
Quarterly SmartPen Sales ExampleUse a simple 3-D formula to display appropriate values in cells B2:F4 from the July, August and September worksheets.
Quarterly SmartPen Sales Example
You could use a simple SUM function to create the totals for Row 5. Instead, practice 3-D cell references by creating a 3-D SUM function in cells B5:F5 to total appropriate values from the July, August and September worksheets.
Range Names•More user-friendly name than column and
row reference.
•Makes calculations more understandable.
• Locate with Find, Go To
• Range Names are absolute
Income Statement
On the Annual worksheet:• Name cell B2 TotRev• Name cell B7 TotExp
Re-enter the Net Income formula to use these range names
Quarterly SmartPen Quantity Example• Assign three range names, one to each total
quantity cell on the July, August and September worksheets.
• Use these range names to calculate the quarterly total quantity on the Quarter worksheet.
• LOOKUP functions display one of MANY possible values depending on the outcome of a logical test.• Often used to translate one value into
another value.
• Requires a lookup table.• Lookup Value is compared to Lookup Table• Can find Exact Match (false) or next closest
value (true)
VLOOKUP Function
1. First column must be used for logical test.
2. First column must contain a value, not a range of values.
3. First column should be in ascending order.
Lookup Table Rules
Lookup Directory Example Solution
1. F1 is compared to first column of lookup table.
2. Extension from Column 2 is displayed for match.
3. False means an exact match must be found.
Assign Colleges Example
In the One Semester file, assign students to colleges depending on their major.
Assign Colleges Example
Setup the list on the Colleges worksheet so that it can be used as a lookup table.
1. No blank rows in a lookup table2. Both college and major must appear on
each row of the lookup table3. The value you want to compare with the
dataset must be the first column4. The first column must be in ascending
order
Assign Colleges Lookup Function
Add a new column to the Grades worksheet labelled College.
Use a VLOOKUP function to assign colleges based on majors.
Assign Grades Example
Use the VLOOKUP function to assign letter grades on a standard 10-point scale based on the average of all four exams.
Assign Grades Lookup TableThe first column must:
• Contain the value for comparison
• Contain only the low end of the range
• Be in ascending order
Quantity Discount ExampleOpen the SmartPen Sales.xlsx file.
Customers get discounts when they order larger quantities of SmartPens.
Use the VLOOKUP function to assign the appropriate unit price based on the quantity ordered.
Start by making sure the lookup table complies with the lookup table rules.
