1 answer:
Answer:
Lin was better than Clare
Step-by-step explanation:
<h3>Given</h3>
<u>Clare
</u>
-
mean: 2,000 grams
- MAD: 275 grams
- median: 2,000 grams
- IQR: 500 grams
<u>Lin
</u>
-
mean: 2,000 grams
- MAD: 225 grams
- median: 1,950 grams
- IQR: 350 grams
<h3 /><h3>Question</h3>
- Which student was better at estimating the mass of the objects?
<h3 /><h3>Solution</h3>
<u>Comparing data for both Clare and Lin, we can see that:</u>
- mean - is same 2000 grams for both
- median - almost same, 2000 grams vs 1950 grams
- MAD - 275 grams vs 225 grams
- IQR - 500 grams vs 350 grams
<u>Conclusion</u>
- Lin was better at estimating than Clare
<u>Reason</u>
- Both students had measures of center (mean and median) very close to 2000 grams
- Lin got less variable responses as both the MAD and IQR were lower than Clare got
