3. INTRODUCTION TO MS-EXCEL
 Excel is a computer program used to create electronic
spreadsheets.
 Within excel user can organize data ,create chart and
perform calculations.
 Excel is a convenient program because it allow user to
create large spreadsheets, reference information, and it
allows for better storage of information.
 Excels operates like other Microsoft(MS) office programs
and has many of the same functions and shortcuts of other
MS programs.

4. OVERVIEW OF EXCEL
 Microsoft excel consists of
workbooks. Within each workbook,
there is an infinite number of
worksheets.
 Each worksheet contains Columns
and Rows.
 Where a column and a row
intersect is called a cell. For e.g.
cell D5 is located where column D
and row 5 meet.
 The tabs at the bottom of the
screen represent different
worksheets within a workbook.
You can use the scrolling buttons
on the left to bring other
worksheets into view. 4

10. Pearson’s product moment method
• Pearson’s Product Moment
Method for calculation of
coefficient of correlation is an
advanced and accurate method. It
is however complicated than rank
difference method. The value of
coefficient of correlation
calculated by using the rank
difference method is not to be
supposed to be technically very
much accurate. It is, therefore,
better to use the Product Moment
Method

14. In the Second step, deviation between scores in the first test and mean of the first group is
calculated by using formula
x =(X-M1 )
For calculating deviation in the second group by using formula
y = (Y-M2)

15. In the third step, square of deviations i.e. x² & y² are obtained. The
sums of squares of deviation are called ∑x² and ∑y².

16. In the Fourth step the value of ∑xy is calculated . Here x and y are multiplied and
then the value of ∑xy is obtained by addition of all ‘+ve’ and all ‘-ve’ xy values
. The value obtained is 16.

17. In the last step, the value of r is calculated by using the formula
r =∑xy/√(∑x²)(∑y²)
The value of ‘r’ obtained in the case is r = 0.235.
