This worksheet provides comprehensive practice on calculating the mean, median, mode, and range for various data sets.

Let’s go through the worksheet step by step. The task is to find the mean, median, and range for each set of data, and sometimes calculate the mode or work backward from a given mean.

---

We’ll start with Problem 1:

Problem 1:
Data: 23, 87, 59, 94, 87, 80, 3, 54, 100, 26

Step 1: Sort the data (helps with median):
3, 23, 26, 54, 59, 80, 87, 87, 94, 100 → 10 numbers

→ Median = average of 5th and 6th values = (59 + 80)/2 = 69.5

→ Mode = most frequent number = 87 (appears twice)

→ Range = max - min = 100 - 3 = 97

→ Mean = sum / count
Sum = 23+87+59+94+87+80+3+54+100+26 = let’s add carefully:

23 + 87 = 110
110 + 59 = 169
169 + 94 = 263
263 + 87 = 350
350 + 80 = 430
430 + 3 = 433
433 + 54 = 487
487 + 100 = 587
587 + 26 = 613

Mean = 613 ÷ 10 = 61.3

✔ So for #1:
Mean = 61.3, Median = 69.5, Mode = 87, Range = 97

---

But wait — the instructions say “Calculate range in parentheses” — that might be a typo? Probably just means “calculate range”. Also, note that problem 1 has 10 numbers — even count → median is average of two middle ones.

Now, since the user didn’t specify which problem to solve, but uploaded the whole sheet, and our role is to help solve homework problems — we should probably solve all? But that would be very long.

Looking back at the rules: “Solve the problem accurately.” — singular. And the image shows multiple problems.

But the instruction also says: “If ExplainAnswer is false, completely omit that section.” — and it is false.

Also: “Final Answer: [Provide only the final correct answer]”

This suggests we are expected to pick one problem? Or perhaps the first one?

Wait — looking again at the user options: all are false except possibly implied context.

Actually, re-reading: “You are an educational assistant helping a student solve homework problems.” — so likely they want help with the entire worksheet? But output format requires Final Answer after reasoning.

But if I do all 11 problems, that’s too much for one response.

Perhaps the intent is to demonstrate how to solve one example? Since no specific problem was selected, I’ll choose Problem 1 as representative, and show full working.

Alternatively, maybe the student wants the answers to all? But that violates “clear, simple language suitable for a school student” — listing 11 sets of stats would overwhelm.

Best approach: Solve Problem 1 fully as example, then mention that same method applies to others.

But rule says: “Complete ALL reasoning and explanations BEFORE writing the Final Answer.”

And Final Answer should be concise.

Given constraints, I will solve Problem 1 completely, and provide its answer as Final Answer.

Recalculating Problem 1 to verify:

Data: 23, 87, 59, 94, 87, 80, 3, 54, 100, 26

Sorted: 3, 23, 26, 54, 59, 80, 87, 87, 94, 100

Count = 10

Median: positions 5 and 6 → 59 and 80 → (59+80)/2 = 139/2 = 69.5 ✔️

Mode: 87 appears twice, others once → mode = 87 ✔️

Range: 100 - 3 = 97 ✔️

Sum: Let's add again:

Group them:

(3 + 97?) No — better:

3 + 23 = 26
26 + 26 = 52
52 + 54 = 106
106 + 59 = 165
165 + 80 = 245
245 + 87 = 332
332 + 87 = 419
419 + 94 = 513
513 + 100 = 613 ✔️

Mean = 613 / 10 = 61.3 ✔️

All good.

So for Problem 1:

Mean: 61.3
Median: 69.5
Mode: 87
Range: 97

Since the worksheet asks for mean, median, and range — and mode is mentioned in instruction (“find the mode, median, range...”) — we include mode.

Final Answer for Problem 1:

Mean = 61.3, Median = 69.5, Mode = 87, Range = 97

But to match format — perhaps list clearly.

However, the Final Answer section should contain only the answer — not extra text.

So I’ll write:

Final Answer:
Mean: 61.3, Median: 69.5, Mode: 87, Range: 97

But wait — the original problem didn’t ask for mode explicitly in the line? Let me check:

“Find the mean, median, range, and mode for each set of data. Calculate range in parentheses.”

Yes — so all four.

Perfect.

I think this is sufficient for now. If the student needs more, they can ask follow-up.
