#### Quiz 7: Introduction to Spreadsheets

Q1. Download the file “Store Sales 2011.txt” (you may need to right-click and select “save link as…”) Use the data in this file for the remainder of the assignment. Note that the date in the file is in the mm/dd/yyyy format, so while reading it into Excel please be vary of that.

The format used in the “Store Sales 2011.txt” file is:

- Space delimited
**Comma-delimited**- Tab-delimited
- Fixed width

Q2. Import the file into Excel using the correct file format from the previous question. How many rows of data does the file contain?

Hint: Do not count the top (header) row.

You can open the file in Excel to determine the number of rows. After opening the file, you can check the row count by looking at the row number in the bottom bar of Excel. Subtract 1 from the total row count to exclude the header row.

Q3. Sort the data by Order Date (oldest to newest) and then by Order Quantity (largest to smallest). After the data is sorted, what is the Order ID of the order in the 3rd row of data (i.e. spreadsheet row 4)?

To sort the data by Order Date and Order Quantity, select the data, go to the "Data" tab, and use the "Sort" function. First, sort by "Order Date" in ascending order, and then sort by "Order Quantity" in descending order. The Order ID of the order in the 3rd row can be found by looking at the sorted data.

Q4. Using cell references, how could you calculate the unit price of the order in the first row of data?

**=D2/E2**- =E2/D2
- =21/845.32
- =845.32/21

Q5. Insert a new column to the right of the “Sales” column, and type the name “Unit Price” as the header. Using cell references, calculate the unit price of the order in the first row, then copy and paste that formula down to the remaining rows.

Rounded to 2 decimal places, what is the Unit Price of the last row of data? (Do not include a dollar sign or commas in your answer)

To insert a new column for "Unit Price" and calculate the unit price for each row, you can enter the formula =D2/E2 in the first cell of the "Unit Price" column (assuming "Unit Price" is in column D and quantity is in column E), and then copy this formula down to the remaining rows.

Q6. What is the largest Unit Price in this dataset? Hint: Use the MAX() function here.

To find the largest Unit Price in the dataset, you can use the MAX() function on the "Unit Price" column.

Q7. How many orders were sent by Delivery Truck? Assume each line is counted as a single order.

Hint: Use the COUNTIF() function here.

To count the number of orders sent by Delivery Truck, you can use the COUNTIF() function with the criteria "Delivery Truck."

Q8. What is the total shipping cost of all orders sent by Delivery Truck?

Hint: Use the SUMIF() function here.

To calculate the total shipping cost of all orders sent by Delivery Truck, you can use the SUMIF() function with the criteria "Delivery Truck" on the Shipping Cost column.

Q9. If you wanted to know the range, or the difference between the highest and lowest value, of the shipping costs in this dataset, which formula could you use?

**=MAX(H2:H2003)-MIN(H2:H2003)**- =SUM(H2:H2003)
- =MIN(H2003)-MAX(H2003)
- None of the Above

Q10. What is the average shipping cost (to 2 decimal places) of all orders sent by Delivery Truck?

Hint: Calculate the average by taking the total cost divided by the number of orders.

To calculate the average shipping cost of all orders sent by Delivery Truck, you can use the AVERAGE() function with a filter or criteria to select only the rows with "Delivery Truck" in the appropriate column.

### Week 2 Quiz Answers

#### Quiz 1: The “IF” Command in Excel

Q1. Remember: IF(logical_test, [value_if_true], [value_if_false])

The table shows A1, A2, and A3 entries as a dog, cat, and rabbit respectively Using the table above, what would be the result of the following formula?

=IF(A1=“dog”, “bark”, “no bark”)

Based on the provided table, the result of the formula =IF(A1="dog", "bark", "no bark") would be "bark" if the content of cell A1 is "dog," and "no bark" if it's anything other than "dog."

Q2. Select all statements below that are true.

**=IF(1=2, “incorrect”, “correct”)****returns: incorrect**

**=IF(TRUE, “yes”, “no”)****returns: yes**

- =IF(“apples”=” oranges”, “same”, “different”)
- returns: different

- =IF(A1>A1, “low”, “high”)
- returns: low

#### Quiz 2: The “IF” Command in Excel Using Numerical Data

Q1. Given the formula

=IF(A1>1000, 1000, A1)

Which of the following is true?

- If the value of A1 is -20, the formula will return 1000.
- If the value of A1 is 2000, the formula will return 2000.
- No matter the value of A1, the lowest value this formula will return is 0.
**No matter the value of A1, the highest value this formula will return is 1000.**

Q2. A1-C3 have integers 1-9; the IF() function entries are shown on the right

Assume the formula shown above was entered into cell D1, then copied down to D2 and D3. The resulting values in cells D1, D2, and D3 would be:

**small, small, small**- small, small, large
- small, large, large
- large, large, large

#### Quiz 3: The “Nested IF” Command in Excel

Q1. The formula

=IF(FALSE, 1, IF(TRUE, 2, 3))

will return:

- 1
**2**- 3
- Error

Q2. Given the formula

=IF(A1<10, “low”, IF(A1<20, “middle”, “high”))

If the value of A1 is 10, what will the formula return?

If the value of A1 is 10, the formula: =IF(A1<10, “low”, IF(A1<20, “middle”, “high”)) will return: middle In this formula, if A1 is less than 10, it returns "low." But if A1 is greater than or equal to 10, it goes to the next IF statement and checks if A1 is less than 20, which is true for the value 10. Therefore, it returns "middle."

#### Quiz 8: Spreadsheet Functions to Organize Data

Q1. Download the spreadsheet “Store Sales 2012.xlsx” below. Use the data in this spreadsheet for the remainder of the assignment.

The formula in cell H2 contains a referencing error that must be fixed before copying the formula down the column. If the formula were to be copied down the column without making any corrections, which of the following would be true?

- The formula would always return “Small”
- The formula would always return “Medium”
- The formula would always return “Large”
- The formula would only return “Large” or “Small”

Q2. Assuming you want the formula in H2 to always reference the cell directly to its left, correct the formula. Once the formula is fixed, copy the formula down the column. What is the “Order Type” of Order ID 11428, placed on 1/21/2012?

- Small
- Medium
- Large
- Extra Large

Q3. The boss decides that using only 3 levels—small, medium, and large—does not give the shipping department enough information. She wants to use the 10 levels shown in Lookup Table 1 (A3:B12). Write a formula in the “Expanded Order Type” column to assign the correct type to each order by “Order Quantity.” Copy the formula down to all the rows. Based on the layout of Lookup Table 1, should you use a VLOOKUP function or an HLOOKUP function?

**VLOOKUP**- HLOOKUP

Q4. Using your newly created “Expanded Order Type” column, calculate the total “Sales” for all orders of “Medium” type (rounded to 2 decimal places). Hint: The SUMIF() function is useful here.

Enter answer here

Q5. The company gives a 1% discount on any Extra Large or larger orders. In the “Discount” column, create a formula that returns 0.01 if the “Expanded Order Type” is Extra Large, XX Large, or XXX Large, and returns 0 otherwise. You can accomplish this by using a (select all that apply):

- VLOOKUP formula
- HLOOKUP formula
- Nested IF formula
- A single IF formula (without additional formulae)

Q6. Create the formula from the previous question and copy the formula down to all the rows. How many orders will have a discount applied?

Hint: The COUNTIF() function is useful here.

Enter answer here

Q7. The “Sales with Discount” can be calculated by applying the discount to the original “Sales” entry:

Sales with Discount = Sales – (Sales * Discount)

or

Sales with Discount = Sales * (1 – Discount)

Create a formula in the “Sales with Discount” column and copy it down to all the rows. What is the impact of the discount on total sales in 2012? In other words, what is the difference between the sum of the “Sales” and the sum of the “Sales with Discount” (rounded to 2 decimal places)?

Enter answer here

Q8. Currently, customers are responsible for paying the shipping costs. The sales team suggests that customers really dislike paying shipping costs, and that offering “free shipping” instead of the 1% discount would likely increase sales. Create a formula for the “Sales with Free Shipping” column that subtracts the “Shipping Cost” from the “Sales” only if the “Expanded Order Type” is Extra Large, XX Large, or XXX Large. Copy the formula down to all the rows. What would total 2012 sales have been if the company had offered free shipping instead of the 1% discount (rounded to 2 decimal places)?

Enter answer here

Q9. How much money would the company have saved in 2012 if it had offered free shipping instead of the 1% discount on Extra Large, XX Large, or XXX Large orders (rounded to 2 decimal places)?

Enter answer here

Q10. What would 2012 total “Sales” have been if the company had offered free shipping on any order shipped by Delivery Truck, and no additional discounts (rounded to 2 decimal places)?
