Why logical functions handle conditions in Google Sheets - Dashboard Impact

Dashboard Mode - Why logical functions handle conditions

Dashboard Goal

Understand how logical functions like IF, AND, and OR help handle conditions in Google Sheets to make decisions automatically.

Sample Data

Student	Score	Attendance (%)
Alice	85	90
Bob	72	75
Charlie	60	80
Diana	95	95
Eva	50	60

Dashboard Components

• KPI Card: Passed Students Count
  Formula: =COUNTIF(B2:B6, ">=70")
  Shows how many students scored 70 or more.
• KPI Card: Perfect Attendance Count
  Formula: =COUNTIF(C2:C6, ">=90")
  Shows how many students have attendance 90% or above.
• Table: Pass/Fail Status
  Formula in D2: =IF(B2>=70, "Pass", "Fail") copied down to D6.
  Shows if each student passed based on score.
• Table: Eligible for Award
  Formula in E2: =IF(AND(B2>=70, C2>=80), "Yes", "No") copied down to E6.
  Shows if student qualifies for award by score and attendance.
• Summary: Any Low Attendance?
  Formula: =IF(COUNTIF(C2:C6, "<70")>0, "Yes", "No")
  Shows if any student has attendance below 70%.

Interactivity

Add a filter for minimum score or attendance percentage. When you change the filter:

• KPI cards update counts based on filtered students.
• Pass/Fail and Eligible for Award tables update to show only filtered students.
• Summary of low attendance updates to reflect filtered data.

Self Check

If you add a filter to show only students with attendance above 80%, which components update and how?

• KPI cards will show counts only for students with attendance > 80%.
• Pass/Fail and Eligible for Award tables will list only those students.
• Summary of low attendance will update to reflect filtered students, possibly showing "No" if none have low attendance.

Key Result

Dashboard shows how logical functions handle conditions to classify student results and attendance.

Practice

1. What does the IF function do in Google Sheets?

easy

A. It checks a condition and returns one value if true, another if false.

B. It adds numbers in a range.

C. It sorts data alphabetically.

D. It counts the number of cells with numbers.

Solution

1. Step 1: Understand the purpose of IF

   The IF function tests a condition and chooses between two results based on true or false.

2. Step 2: Compare options with IF's behavior

   Only It checks a condition and returns one value if true, another if false. describes this behavior correctly; others describe different functions.

3. Final Answer:

   It checks a condition and returns one value if true, another if false. -> Option A

4. Quick Check:

   IF function = condition check [OK]

Hint: IF means choose between two results based on true or false [OK]

Common Mistakes:

• Confusing IF with SUM or COUNT functions
• Thinking IF sorts data
• Assuming IF counts cells

2. Which of these is the correct syntax for the IF function in Google Sheets?

easy

A. =IF{condition, value_if_true, value_if_false}

B. =IF(condition, value_if_true, value_if_false)

C. =IF(condition; value_if_true; value_if_false)

D. =IF[condition, value_if_true, value_if_false]

Solution

1. Step 1: Recall Google Sheets formula syntax

   Google Sheets uses commas to separate arguments in functions.

2. Step 2: Identify correct IF syntax

   =IF(condition, value_if_true, value_if_false) uses commas and parentheses correctly; others use wrong separators or brackets.

3. Final Answer:

   =IF(condition, value_if_true, value_if_false) -> Option B

4. Quick Check:

   Correct IF syntax uses commas and parentheses [OK]

Hint: Use commas inside parentheses for IF arguments [OK]

Common Mistakes:

• Using semicolons instead of commas
• Using curly braces or square brackets
• Missing parentheses

3. Given the formula =IF(A1>10, "High", "Low") and cell A1 contains 8, what will the formula return?

medium

A. TRUE

B. "High"

C. 8

D. "Low"

Solution

1. Step 1: Evaluate the condition A1>10

   Since A1 is 8, 8>10 is FALSE.

2. Step 2: Determine IF result based on condition

   Because condition is FALSE, IF returns the value_if_false, which is "Low".

3. Final Answer:

   "Low" -> Option D

4. Quick Check:

   8>10 is false, so result = "Low" [OK]

Hint: Check condition first, then pick true or false result [OK]

Common Mistakes:

• Assuming condition is true without checking
• Returning the cell value instead of IF result
• Confusing TRUE/FALSE with text results

4. The formula =IF(A1=5, "Yes", "No" is entered in a cell. What is wrong with this formula?

medium

A. Text values should not be in quotes.

B. Using = instead of == for comparison.

C. Missing closing parenthesis at the end.

D. IF function cannot compare numbers.

Solution

1. Step 1: Check formula syntax

   The formula has an opening parenthesis after IF but no closing parenthesis at the end.

2. Step 2: Verify other parts

   Using = for comparison is correct in Sheets, text in quotes is correct, and IF can compare numbers.

3. Final Answer:

   Missing closing parenthesis at the end. -> Option C

4. Quick Check:

   All functions need matching parentheses [OK]

Hint: Count parentheses to avoid missing one [OK]

Common Mistakes:

• Using double equals (==) like in programming
• Not putting text in quotes
• Thinking IF can't compare numbers

5. You want to create a formula that returns "Pass" if a student's score in cell B2 is 50 or more, and "Fail" otherwise. Which formula correctly uses logical functions to handle this condition?

hard

A. =IF(B2>=50, "Pass", "Fail")

B. =IF(B2>50, "Pass", "Fail")

C. =IF(B2=50, "Pass", "Fail")

D. =IF(B2<50, "Pass", "Fail")

Solution

1. Step 1: Understand the condition for passing

   Passing means score is 50 or more, so condition is B2 >= 50.

2. Step 2: Check each formula against the condition

   =IF(B2>=50, "Pass", "Fail") uses B2 >= 50 correctly. =IF(B2>50, "Pass", "Fail") excludes 50, =IF(B2=50, "Pass", "Fail") only checks exactly 50, =IF(B2<50, "Pass", "Fail") reverses logic.

3. Final Answer:

   =IF(B2>=50, "Pass", "Fail") -> Option A

4. Quick Check:

   Use >= for 50 or more condition [OK]

Hint: Use >= to include the boundary value [OK]

Common Mistakes:

• Using > instead of >= and missing exact 50
• Checking only equality (=50)
• Reversing true/false results
