It is hypothesised that the participants exposed to the audio will rate the female presenter higher on the ﬁrst impression scale based on verbal cues compare to the participants exposed to the video of the presenter or nonverbal cues. Proposal: Participants are randomly allocated in this experimental design where there are two groups and each group is exposed to a manipulated independent variable either an audio clip (verbal cues) or a video clip (nonverbal cues). The dependant variable in this case will be determined by how the participants score the female presenter based on verbal or nonverbal cues. The data evaluates how the verbal and nonverbal cues had an impact on ﬁrst impressions formed by the participants. The maximum score that can be achieved by the presenter on the ﬁrst impression scale is 1300. By calculating the mean score of the participants who were exposed to the video of the presenter and comparing it to the mean score of the participants who were exposed to the audio of the presenter we can evaluate whether verbal and nonverbal cues have an effect on forming ﬁrst impressions. The data will be illustrated on a graph which represents the mean score of both groups. If the hypothesis is supported the data will clearly indicate this by showing a higher mean with a magnitude difference of 10% for the participants exposed to the verbal cues over participants exposed to the nonverbal cues.
Introduction Data was collected from 49 participants who were required to evaluate a female presenter on the First Impression Scale (FIS). The purpose of this experiment was to determine what factors affect an individuaI's ﬁrst impression on a person. Participants were divided into two groups and were exposed to either a audio clip or a video clip. Participants were asked to rate the female presenter on the FIS scale in according to their impression of her. The information then was used to test the hypothesis by summarising the data into a chart and a bar graph illustrating the mean score for the participants who were exposed to non verbal cues and compared to participants who were exposed to verbal cues. Since the hypothesis is related to a magnitude of difference the means of the two groups were converted into a percentage. Where we examine which percentage ofthe group had a favourable impression of the female presenter. The percentage was also compared by a bar graph to illustrate any difference and by how much. By comparing the means and the percentage of the two groups it will show whether verbal or nonverbal cues have an impact on the formation of a positive or a negative ﬁrst impression of an individual. Furthermore the experiment will show whether non verbal cues or verbal cues have a bigger effect on the formation of a positive ﬁrst impression on an individual. If the hypothesis is correct the data should clearly illustrate this by not only showing a higher mean for the group which was exposed to the verbal cues but it should also show a higher percentage of the verbal group 2
having a favourable or positive impression of the female presenter over the group which was exposed to non verbal cues.
Independent Variable Mean for Group 1,3 (Non Verbal) Mean for Group 2,4 (Verbal) Difference Between the Means
Dependent Variable 854.12 811.28 42.84
Mean Scores on FIS Scale
Mean for Verbal
Mean for Non Verbal
When looking at the results of the experiment it is ok that one group had a higher mean on the FIS than the other. The results helped to answer the question whether there is a difference between forming...
