Please make relevant to MARKETING research!
SOLUTION;-
Market research involves data collection process by
distributing the questionnaires among
specific group of respondents. Further, this collected data is put
for different analysis methods to
draw various interpretations. Anova. which is also known as
analysis of variance is one of the
statistical model to test the significance difference of means
between group of respondents and
then compares the variance of responses within the
groups
The reason for using the statistical model Anova is to
test whether averages (means) of various
groups in the data set is same or not. For Instance: Consider the
set of 50 sample of data. All
these 50 samples are from different genders. Now. Anova test would
tell whether the average
respondents of male and female are same or not. This means whether
average participants of
female are equal to average participants of male. So, here variance
is considered thus, it is
called analysis of variance. The reason we would try to know the
means of different groups is tobuild the profile of major users and
take decisions based on that.
