Atown hosts an arbor day celebration. each of the 105 families attending gets to choose a sapling to take home as they leave. michelle and ari each design surveys in order to determine the average height of the saplings. michelle samples the first 20 families leaving the celebration. ari samples every fifth family leaving the celebration. which best explains which student’s sample is likely to produce more valid results? michelle’s because she sampled the saplings of every family in her group
michelle’s because she sampled the saplings of the first 20 families to choose their saplings
ari’s because she sampled saplings chosen at different times
ari’s because she sampled one more sapling than michelle sampled

Ari’s because she sampled saplings chosen at different times.

Michelle samples the first 20 families leaving the celebration.

Ari samples every fifth family leaving the celebration.

Ari's sample is likely to produce more valid results.

This is because she is selecting every fifth sample and this is the reason, she can see variability in the data. This can produce more valid results.

Michelle is asking the first 20 numbers, this can give a different median from the rest of the data whereas Ari is collecting close values of median of the whole data, this will help her give accurate results.

So, correct option is : Ari’s because she sampled saplings chosen at different times.
