Topic quiz 5: Conditional formatting, data validation and duplicates

  1. Question 1 of 17

    On which ribbon tab do you find the Conditional Formatting button?
    Show answer

    Answer: C. Home

    Conditional Formatting is on the Home tab, in the Styles group.

  2. Question 2 of 17

    You want each amount to show a coloured bar inside its cell, longer for larger numbers. Which conditional format do you pick?
    Show answer

    Answer: D. Data Bars

    Data Bars show each value's size as a coloured bar in the cell.

  3. Question 3 of 17

    Icon Sets split a range into groups of values, each with its own icon. How many groups can an icon set have?
    Show answer

    Answer: B. 3 to 5

    An icon set sorts values into three to five groups, and each group has its own threshold.

  4. Question 4 of 17

    You want to quickly highlight the 10 largest sales in a column. Which menu do you use?
    Show answer

    Answer: C. Conditional Formatting > Top/Bottom Rules > Top 10 Items

    Top/Bottom Rules > Top 10 Items highlights the highest values in the range without changing the order of the data.

  5. Question 5 of 17

    How do you highlight email addresses that appear more than once in a column?
    Show answer

    Answer: C. Conditional Formatting > Highlight Cells Rules > Duplicate Values

    Duplicate Values highlights repeated entries so you can review them. Remove Duplicates deletes them instead.

  6. Question 6 of 17

    You select B2:B20 (B2 is the active cell) and want to colour each cell when the value in column E of the same row is over 300. Which rule formula do you enter?
    Show answer

    Answer: C. =E2>300

    Write the formula for the active cell with a relative reference (E2), so it adjusts for every row. $E$2 would check only row 2.

  7. Question 7 of 17

    You type A2>B2 (with no equal sign) as a conditional formatting formula. What happens?
    Show answer

    Answer: A. Excel adds quotes, so the rule is read as text and fails

    Microsoft warns that if you leave out =, Excel adds = and quotes, and you must remove the quotes before the formula works.

  8. Question 8 of 17

    Two rules apply to B2:B10: "greater than 60,000: blue fill" is above "greater than 70,000: yellow fill" in the Rules Manager. B2 holds 75,000. What fill does B2 get?
    Show answer

    Answer: C. Blue

    When conflicting rules apply, the rule higher in the list has precedence. 75,000 is over 60,000, so the blue rule wins. Use Move Up/Move Down to change the order.

  9. Question 9 of 17

    In the Conditional Formatting Rules Manager, what does the Stop If True box do?
    Show answer

    Answer: C. Lower rules are not checked when this rule is true

    Stop If True stops rule evaluation at that rule, so lower rules are not applied to those cells.

  10. Question 10 of 17

    Which command lets you make a drop-down list in a cell?
    Show answer

    Answer: A. Data > Data Validation, then Allow: List

    In the Data Validation box, choose List in Allow, then type the items separated by commas (for example Low,Average,High) in Source.

  11. Question 11 of 17

    You want a cell to accept only whole numbers from 1 to 40. What do you choose in Data Validation?
    Show answer

    Answer: A. Whole Number, between, minimum 1 and maximum 40

    Whole Number limits the cell to whole numbers, and "between" sets lower and upper limits.

  12. Question 12 of 17

    Which Error Alert style stops people from entering a value that breaks the rule?
    Show answer

    Answer: A. Stop

    Stop prevents invalid data; the user can only retry or cancel. Warning and Information let the user keep the value.

  13. Question 13 of 17

    You added a validation rule to a column that already had data. How can you find old entries that break the rule?
    Show answer

    Answer: B. Use Circle Invalid Data

    Excel does not warn you about existing invalid data. Circle Invalid Data draws circles around those cells.

  14. Question 14 of 17

    A co-worker pastes values into a cell that has data validation. What happens?
    Show answer

    Answer: C. It may get through, since validation checks typed entries

    Microsoft says data validation shows messages and blocks invalid entries only when users type directly in a cell. Copied or filled data can bypass it.

  15. Question 15 of 17

    You select A1:C8 below and use Data > Remove Duplicates with all three columns checked. How many data rows are left?
    ABC
    1NameEmailShift
    2Ana Diazana@example.comDay
    3Ben Coleben@example.comNight
    4Ana Diazana@example.comDay
    5Chen Wuchen@example.comDay
    6Ben Coleben@example.comDay
    7Dina Roydina@example.comNight
    8Chen Wuchen@example.comDay
    Show answer

    Answer: B. 5

    A row is removed only if all checked columns match an earlier row. Ana Diaz/Day and Chen Wu/Day repeat; Ben Cole has Night and Day, so both stay: 7 - 2 = 5.

  16. Question 16 of 17

    You select A1:C8 below and use Remove Duplicates with only the Email column checked. How many data rows are left?
    ABC
    1NameEmailShift
    2Ana Diazana@example.comDay
    3Ben Coleben@example.comNight
    4Ana Diazana@example.comDay
    5Chen Wuchen@example.comDay
    6Ben Coleben@example.comDay
    7Dina Roydina@example.comNight
    8Chen Wuchen@example.comDay
    Show answer

    Answer: B. 4

    Now only Email is compared, so each email address is kept once: ana, ben, chen and dina.

  17. Question 17 of 17

    In the sheet below, what does =UNIQUE(B2:B8,FALSE,TRUE) return?
    ABC
    1NameEmailShift
    2Ana Diazana@example.comDay
    3Ben Coleben@example.comNight
    4Ana Diazana@example.comDay
    5Chen Wuchen@example.comDay
    6Ben Coleben@example.comDay
    7Dina Roydina@example.comNight
    8Chen Wuchen@example.comDay
    Show answer

    Answer: D. dina@example.com

    With exactly_once set to TRUE, UNIQUE returns only values that appear exactly once. Only dina@example.com appears once.
