About SPSS

There are many different software programs designed for use with

quantitative.

SPSS, which stands for Statistical Package for Social Science, is the

most popular quantitative analysis software program used in social

science research.

It is comprehensive and flexible and can be used with almost any type

of file.

It can be used to generate tabulated reports, charts, and plots of

distributions and trends, as well as generate descriptive statistics and

more complex statistical analyses.

Step 3

Step 4

If probability value is less then 10% then it is significant.

.329 is more then 10% then it is insignificant.

.020 is less then 10% then it is significant.

.681 is more then 10% it is insignificant.

.000 is less then 10 % it is significant.

Probability Significant or Insignificant

If t value is more then 2 is a thumb rule then it is significant.

1.006 is less then 2 then it is insignificant.

2.580 is more then 2 then it is significant.

0.419 is less then 2 then it is significant.

4.805 is more then 2 then it is significant.

Individual observation Significant or Insignificant

Calculate t value

If t value is not given then we calculate t value by B divided Std.Error.

24.152 / 24.012 = 1.006

-0.534 / 0.207 =-2.580

0.082 / 0.196 = 0.419

0.514 / 0.107 = 4.805

Estimation of Equation

Y= B0 +B1 X1 + B2 X2 + B3 X3

Y=24.152 - 0.534P +0.82I + 0.514PS

Interpretation:

If there is one unit increased in income then p (price)

will decreased 0.534.

Overall Model Significant or

Insignificant

F.st is 2.18 which is significant that represent the

over all model significant.

Calculate R2

R2 = .99 %

Independent variable depend on dependent variable. if R is 15 %

then it is insignificant.

Conclusion

It is easy to learn and use.

Its includes a full range of data, management of system and

editing tools.

Its provide in-depth statistical capabilities.

Its offer complete plotting, reporting and presentation

features
