How To Perform An Independent T-Test In SPSS Top Tip Bio
Testing of Assumptions In statistical analysis , all parametric tests assume some certain characteristic about the data, also known as assumptions. Violation of these assumptions changes the conclusion of the research and interpretation of the results.... Inputting a data in SPSS is not easy because there are many things to do but when you know the steps on how to input data, you will never have a hard time. Just be sure to open the program, click on the Variable View, choose the data and enter the data, then press OK.

The independent, or unpaired, t-test is a statistical measure of the difference between the means of two independent and identically distributed samples. For example, you may want to test to determine if there is a difference between the cholesterol levels of men and women. This test computes a t value for the data that is then related to a p-value for the determination of significance. One of... 1) Data are a proportion ranging between 0.0 - 1.0 or percentage from 0 - 100. 2) Most data points are between 0.2 - 0.8 or between 20 and 80 for percentages. This transformation yields radians (or degrees) whose distribution will be closer to normality.

SPSS Help Provides General Info on Nonparametric Tests. In order to understand the idea of nonparametric statistics you should first find out about parametric statistics which is basically an ability to make prediction about a variable and how it will behave in different environments.
- Non-parametric Tests Using SAS social and behavioral sciences, observations are difficult or impossible to take on numerical scales and a suitable nonparametric test is …
- SPSS will report that your p-value is equal to .000 if it is less than .001. If you see this, then you should simply report that p <.001. † To summarize the steps to a hypothesis test 1. Determine your null and alternative hypotheses. 2. Draw a sample from the population of interest. 3. Collect data that can be used to discriminate the null and alternative hypotheses. 4. Calculate a test

- The objective of the study is to determine whether the type of analyses conducted on Likert scale data affect the conclusion drawn from the results obtained. 1.4 Associated significance of study It is hoped that the determination of the effect of conducting parametric or non-parametric tests on Likert scale data will enable researchers, especially those new to the field of research, students
