Drawing conclusions from data

A statement that answers a question using evidence from the data, such as numbers. It should only say what the data shows and stay within the data's limits.

Understanding Drawing conclusions from data in Years 5–6 Data & Information

What it does: The numbers 15 and 5 are the evidence that supports the conclusion that dogs are more popular. The conclusion directly answers the question by naming the sport and giving the evidence. Data has limits. We only asked 20 Year 5 students, so we can't say what everyone in Australia thinks. A conclusion must be backed by evidence from the data. Guesses with no evidence do not belong in it. The data only shows how many walk and how many ride. It says nothing about health, so that conclusion goes beyond the data. The statement answers the question about favourite lunch and backs it up with numbers from the survey.

Common mistakes: The question must be one the data can answer. The data counts votes, so it cannot show which pet is cutest. It should ask which pet got the most votes. The conclusion goes against the data. Wednesday was 19 degrees, which is the coolest day. The warmest day was Tuesday at 24 degrees.

Quick Questions

1. Which is a conclusion that uses numbers as evidence?
A. Most of our class likes pizza best: 18 out of 25 students chose it. ✓
B. Pizza is just the best food ever.
A good conclusion uses numbers from the data, like 18 out of 25, as evidence.
2. A class survey asks: Which pet do students like most? The results are dogs 12, cats 8, fish 5. Which conclusion answers the question?
A. Dogs are the most liked pet, with 12 votes. ✓
B. Fish are boring because only 5 students picked them.
A conclusion should answer the question that was asked. The answer is dogs, and 12 votes is the evidence.
3. Our survey only asked 20 students in Year 5. Which conclusion stays within the data's limits?
A. Most Year 5 students we asked prefer swimming. ✓
B. Everyone in Australia prefers swimming.
Data has limits. We only asked 20 Year 5 students, so we can't say what everyone in Australia thinks.
4. True or false: A conclusion can include things the data does not show.
A. True. A conclusion can include guesses with no evidence.
B. False. A conclusion only says what the data shows. ✓
A conclusion must be backed by evidence from the data. Guesses with no evidence do not belong in it.
5. A graph shows 15 students walk to school and 10 students ride a bike. Which conclusion is correct?

B. More students walk to school than ride a bike. ✓
The data only shows how many walk and how many ride. It says nothing about health, so that conclusion goes beyond the data.

Spot the Error

Question 1
A Q: Which pet is the cutest?
B Data: Cat 12, Dog 9, Fish 4
C Conclusion: Cats got the most.
Line A — The question must be one the data can answer. The data counts votes, so it cannot show which pet is cutest. It should ask which pet got the most votes.
Question 2
A Q: Which day was warmest?
B Data: Mon 21, Tue 24, Wed 19
C Conclusion: Wed was warmest.
Line C — The conclusion goes against the data. Wednesday was 19 degrees, which is the coolest day. The warmest day was Tuesday at 24 degrees.
Question 3
A Data: 15 yes, 5 no (20 pupils)
B Conclusion: All kids like it.
C Limit: Only Year 6 was asked.
Line B — The data shows 15 of 20 pupils said yes, not all kids. A conclusion should only say what the data shows, such as 15 of 20 like it.
Question 4
A Q: Which lunch sells the most?
B Data: Pie 30, Roll 45, Salad 8
C Conclusion: Rolls sold most.
D Limit: Rolls will always win.
Line D — A limit says what the data cannot tell us. One week of data cannot prove rolls will always win. It should say the data is only from one week.
Question 5
A Total: 8 + 5 + 11 = 22 books
B Conclusion: We read 24 books.
C Limit: Only 3 pupils counted.
Line A — The number used as evidence is wrong. 8 + 5 + 11 equals 24, not 22. The conclusion then says 24, so the evidence must match.
