Meaning of research
The word
research is composed of two syllables, ‘re’ and ‘search’. Search is defined as
a verb meaning ‘to examine closely and carefully’, ‘to test and try’, or ‘to

of Measurement Scales
The term
‘measurement’ means assigning numbers or some other symbols to the
characteristics of certain objects. Scaling is an extension of measurement.

a two-way analysis of variance and interpret the result.
(Meaning,
Assumptions and examples, Formulas, Calculation, Solution and Interpretation to
the problem) 4, 6(10 marks)
Answer.
a)
Meaning of analysis of variance
Suppose we know
that the sales of a product is influenced by the price level. In this case,
sales are a dependent variable and the price is the independent variable. Let
there be three levels of price, namely, low, medium and high. We wish to determine
the most effective price level i.e. at which price level the sale is highest.
Here, the test units are the stores which are randomly assigned to the three
treatment level. The average sales for each price level is computed and
examined to see whether there is any significant difference in the sale at
various price levels. The statistical technique to test for such a difference
is called analysis of variance (ANOVA).
Q6.
