Attempts: Keep the Highest: /3 Aa Aa 1. Identifying paired samples For each of the following research scenarios, decide whether the design uses a paired sample. If the design uses a paired sample, identify whether it uses matched samples or repeated measures. (Note: Here, "repeated measur describes two measurements on the same participant.) es" You design a study to examine whether a group of anorexic women has higher intelligence than the general population, which has an average IQ of 100 with a standard deviation of 15. uses a paired sample (matched samples) uses a paired sample (matched samples) The design described uses a paired sample (repeated measures) in Imecuer doss not use arvesrear samre avout Tww clean their cars are.

The design does not describe a paired sample.
A paired t test must be used if you want to compare two sample means and there is anintrinsic relationship between the observations collected in both samples. In other words,the observations in one sample were sampled randomly and independently, but theobservations in the second sample were dependent upon the first. For instance, if thesame individual is sampled each time, there is an obvious relationship between thesamples and they are not independent.
