Question: A developmental psychologist is interested in the attention of infants to human faces. To study this, he shows infants either a set of geometric figures or a photograph of a human face. He then records the number of seconds the infants look at the stimuli (geometric figures or faces) without looking away for more than 5 seconds. Infants who attend for more than 100 seconds are given a score of 100. The data is as follows:

Geometric Figures

Number of seconds f

Faces

Number of Seconds f

Determine the three measures of central tendency. Which is the most appropriate for this experiment? Suppose we discard the data for the three infants who attended for more than \(100\) seconds. Recalculate the measures of central tendency and tell which is most appropriate.
