The Grade Book Problem
Solution
Other Requirements

3. 1. Grade Book Problem
Create an Open office Calc file named GradeBook.ods and then input data as shown in the following table:

4. Format the worksheet appropriately
The first calculation will be Test Average which must be the averaging value of Test 1, Test 2, Test 3 and Test 4.
In the column G, find the rank of values in the column F.
Use the appropriate function to find the maximum value of Test Values in the cell F14.
Similarly, the minimum value is determined by find the min value in the column F.
Count the number of students in the list above.

5. 2. Solution 2.1. Create the Worksheet 2.2. Format the Worksheet
2.3. Calculate the Test Average
2.4. Look up the Rank
2.5. Find the Max Value
2.6. Find the Min Value
2.7. Count the Number of Students

6. 2.1. Create the worksheet
Create a Open Office Calc named: GradeBook.ods
Input raw data

7. 2.2. Format the Worksheet
Change the background color for the ranges A1:G3 and D14:D16.
Align Centered for column header, then change font style to Bold
Merge two cells for D14, D15, and D16.

8. 2.3. Calculate the Test Average
AVERAGE function returns the average of the arguments.
- Syntax: AVERAGE(Number 1; Number 2; ...)‏
or ‏AVERAGE(range)‏
= AVERAGE(B4:E4)‏

9. 2.4. Look up the Rank
RANK function returns the rank of a number in a sample.
- Syntax: RANK(Value; Data; Type)‏
Value is the value, whose rank is to be determined.
Data is the array or range of data in the sample
Type (optional) is the sequence order.
- Type = 0 means descending from the last item of the array to the first (this is the default).
- Type = 1 means ascending from the first item of the range to the last.

10. = RANK(F4;$F$4:$F$12)‏

11. 2.5. Find the Max Value
MAX function returns the maximum value in a list of arguments.
- Syntax: MAX(Number 1; Number2; ...)‏
or MAX(range)‏
= MAX(F4:F12)‏

12. 2.6. Find the Min Value
MIN function returns the minimum value in a list of arguments.
- Syntax: MIN(Number 1; Number 2; ...)‏
or MIN(range)‏
= MIN(F4:F12)‏

13. 2.7. Count the Number of Students
COUNT function counts how many numbers are in the list of arguments. Text entries are ignored.
- Syntax: COUNT(value1; value2; ...)‏
or COUNT(range)‏
= COUNT(F4:F12)‏

14. 3. Other Requirements
Insert a new column between column F and G and type Grade as column header.
Beginning with the cell J3, enter data for the Grading Criteria as shown in the following table.
The grade is determined by looking up the value in the lookup table. Use the lookup table in cells J4:K9 with a VLOOKUP function to determine the Grade.

15. Solution 3.1. Insert a new column 3.2. Enter the Grading Criteria
3.3. Looking up the Grade value

16. 3.1. Insert a new column

17. 3.2. Enter the Grading Criteria

18. 3.3. Looking up the Grade value
Vertical search with reference to adjacent cells to the right.
- Syntax: VLOOKUP(Search criterion;array;
index;Sort order)‏
Search criterion is the value searched for in the first column of the array.
array is the reference, which is to comprise at least two columns.
index is the number of the column in the array that contains the value to be returned. The first column has the number 1.
Sort order is an optional parameter that indicates whether the first column in the array is sorted in ascending order. Enter the Boolean value FALSE if the first column is not sorted in ascending order.

19. = VLOOKUP(F4;$J$4:$K$8;2)‏
