In science class, Clare and Lin estimate the mass of eight different objects that actually weigh 2,000 grams each.

Lin was better than Clare

Step-by-step explanation:

Given

Clare

mean: 2,000 grams MAD: 275 grams median: 2,000 grams IQR: 500 grams

Lin

mean: 2,000 grams MAD: 225 grams median: 1,950 grams IQR: 350 gramsQuestionWhich student was better at estimating the mass of the objects?Solution

Comparing data for both Clare and Lin, we can see that:

mean - is same 2000 grams for bothmedian - almost same, 2000 grams vs 1950 gramsMAD - 275 grams vs 225 gramsIQR - 500 grams vs 350 grams

Conclusion

Lin was better at estimating than Clare

Reason

Both students had  measures of center (mean and median) very close to 2000 gramsLin got less  variable responses as  both the MAD and IQR were lower than Clare got
