Question

In a problem-solving experiment with n=100 children, 5 of the children failed to complete the problem within 10 minutes and were simply marked as “failed”. If the experimenter wanted to find a measure of central tendency to describe the average amount of time needed to complete the problem, what measure should be used? Explain. (2 points

Answer #1

Thank you.

In a problem-solving experiment with n=100 children, 5 of the
children failed to complete the problem within 10 minutes and were
simply marked as “failed”. If the experimenter wanted to find a

A school psychologist is interested in whether time has changed
the problem with student parking that has been discussed for a few

amount of time to find parking for students is 15 minutes (µ=15).
The current sample’s information is as follows: M=19 minutes and a
S= 6...
