Question

Peter's job is to watch videos of children interacting with other children and estimate the physical distances between the children. If Peter is simply not good at estimating distances, ____ error will be introduced.

A. Participant
B. Construct
C. Observer
D. Environmental

Answer 1

When Peter, who is poor at estimating distances, watches videos of children for research purposes, his inaccuracies would introduce observer error into the data collected.

Step-by-step explanation:

If Peter is simply not good at estimating distances, observer error will be introduced. This type of error occurs when the person making the observation fails to measure or perceive the phenomena accurately. In Peter's case, being unable to estimate distances correctly would lead to inaccurate data on the physical proximity of children interacting with each other, potentially skewing the results of the research. To mitigate this, clear criteria for measuring and classifying behaviors must be established for observers, and inter-rater reliability can be assessed by comparing observations of the same events by different observers.
