Below is one detailed approach to solving the problem:
──────────────────────────────
Step 1. Entering the Data
──────────────────────────────
Open your preferred spreadsheet program (e.g., Microsoft Excel) and create a new worksheet. Enter the following data into the cells:
[tex]\[
\begin{array}{|c|c|c|c|c|c|c|}
\hline
\text{S/N} & \text{NAME} & \text{SEX} & \text{HIST} & \text{CRE} & \text{GEO} & \text{COMP} \\
\hline
1 & F & \quad & 90 & 54 & 78 & 50 \\
\hline
2 & M & \quad & 79 & 53 & 70 & 89 \\
\hline
3 & F & \quad & 87 & 65 & 69 & 65 \\
\hline
4 & F & \quad & 76 & 57 & 82 & 45 \\
\hline
5 & F & \quad & 45 & 66 & 55 & 76 \\
\hline
6 & M & \quad & 76 & 44 & 76 & 87 \\
\hline
\end{array}
\][/tex]
After entering the data, save your worksheet as “S .4 mark sheet.”
──────────────────────────────
Step 2. Calculating the Total Marks (TOT Column)
──────────────────────────────
For each student, calculate the total marks by summing the scores in the four subjects. For a student with subject marks [tex]$a$[/tex], [tex]$b$[/tex], [tex]$c$[/tex], and [tex]$d$[/tex], the total is given by:
[tex]$$
\text{Total} = a + b + c + d
$$[/tex]
Using the scores provided, the total marks for each student are:
- Student 1:
[tex]$$
90 + 54 + 78 + 50 = 272
$$[/tex]
- Student 2:
[tex]$$
79 + 53 + 70 + 89 = 291
$$[/tex]
- Student 3:
[tex]$$
87 + 65 + 69 + 65 = 286
$$[/tex]
- Student 4:
[tex]$$
76 + 57 + 82 + 45 = 260
$$[/tex]
- Student 5:
[tex]$$
45 + 66 + 55 + 76 = 242
$$[/tex]
- Student 6:
[tex]$$
76 + 44 + 76 + 87 = 283
$$[/tex]
Enter these totals in a new column labeled “TOT.”
──────────────────────────────
Step 3. Calculating the Average Marks (AVE Column)
──────────────────────────────
For each student, compute the average mark by dividing the total marks by [tex]$4$[/tex] (since there are 4 subjects):
[tex]$$
\text{Average} = \frac{\text{Total Marks}}{4}
$$[/tex]
The results are:
- Student 1:
[tex]$$
\frac{272}{4} = 68.0
$$[/tex]
- Student 2:
[tex]$$
\frac{291}{4} = 72.75
$$[/tex]
- Student 3:
[tex]$$
\frac{286}{4} = 71.5
$$[/tex]
- Student 4:
[tex]$$
\frac{260}{4} = 65.0
$$[/tex]
- Student 5:
[tex]$$
\frac{242}{4} = 60.5
$$[/tex]
- Student 6:
[tex]$$
\frac{283}{4} = 70.75
$$[/tex]
Record these averages in a new column labeled “AVE.”
──────────────────────────────
Step 4. Determining the Highest Scores
──────────────────────────────
In cell [tex]$B10$[/tex], type the label “Highest Score.” Then, for each subject and for the total and average columns, determine the highest value:
- \textbf{History (HIST):} The highest score is [tex]$90$[/tex].
- \textbf{CRE:} The highest score is [tex]$66$[/tex].
- \textbf{Geography (GEO):} The highest score is [tex]$82$[/tex].
- \textbf{Computer (COMP):} The highest score is [tex]$89$[/tex].
- \textbf{TOTAL MARKS:} The highest total is [tex]$291$[/tex].
- \textbf{AVERAGE MARK:} The highest average is [tex]$72.75$[/tex].
You may use functions such as \texttt{MAX} in the spreadsheet to compute these.
──────────────────────────────
Step 5. Determining the Lowest Scores
──────────────────────────────
In cell [tex]$B11$[/tex], type the label “Lowest Score.” Next, find the lowest scores for each subject and for the total and average columns:
- \textbf{History (HIST):} The lowest score is [tex]$45$[/tex].
- \textbf{CRE:} The lowest score is [tex]$44$[/tex].
- \textbf{Geography (GEO):} The lowest score is [tex]$55$[/tex].
- \textbf{Computer (COMP):} The lowest score is [tex]$45$[/tex].
- \textbf{TOTAL MARKS:} The lowest total is [tex]$242$[/tex].
- \textbf{AVERAGE MARK:} The lowest average is [tex]$60.5$[/tex].
Again, you can use the \texttt{MIN} function to perform these calculations.
──────────────────────────────
Summary of the Calculated Results
──────────────────────────────
The totals, averages, highest scores, and lowest scores are as follows:
[tex]\[
\begin{array}{ll}
\textbf{Total Marks (TOT)}: & [272, \ 291, \ 286, \ 260, \ 242, \ 283] \\
\textbf{Average Marks (AVE)}: & [68.0, \ 72.75, \ 71.5, \ 65.0, \ 60.5, \ 70.75] \\
\textbf{Highest Scores:} & \begin{array}{l}
\text{HIST: } 90 \\
\text{CRE: } 66 \\
\text{GEO: } 82 \\
\text{COMP: } 89 \\
\text{Total: } 291 \\
\text{Average: } 72.75
\end{array} \\
\textbf{Lowest Scores:} & \begin{array}{l}
\text{HIST: } 45 \\
\text{CRE: } 44 \\
\text{GEO: } 55 \\
\text{COMP: } 45 \\
\text{Total: } 242 \\
\text{Average: } 60.5
\end{array}
\end{array}
\][/tex]
──────────────────────────────
Final Remarks
──────────────────────────────
After entering all the data and writing the formulas (using formulas such as \texttt{=SUM()} for the totals, \texttt{=AVERAGE()} or division by 4 for the averages, \texttt{=MAX()} for highest values, and \texttt{=MIN()} for lowest values), double-check your cells to ensure that all calculations are correct. Save your worksheet.
This concludes the step-by-step solution with all the calculated results as mentioned above.
