Question

question 1 (1 point)
in science class, clare and lin estimate the mass of eight different objects that actually weigh 2,000 grams each.
some summary statistics:
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 grams

which student was better at estimating the mass of the objects? explain your reasoning.
______ (lin, clare) was better at estimating than ____ (lin, clare) because both students had measures of center very close to 2,000 grams, but ____ (lins, clares) responses were ______ (less, more) variable as determined by both the mad and the iqr.

blank 2:
blank 3:
blank 4:

Explanation:

Step1: Understand the measures

Measures of center (mean, median) are close for both. MAD (Mean - Absolute - Deviation) and IQR (Inter - Quartile Range) measure variability. Lower values mean less variability.

Step2: Compare MAD and IQR

Clare's MAD is 275 grams and IQR is 500 grams. Lin's MAD is 225 grams and IQR is 350 grams. Lin has lower MAD and IQR.

Answer:

Lin, Clare, Lin, less
