Statistical Analysis

1. Forming a Research Question

During the Literature Review, Codes are marked as:

  • Independent Variables

  • Dependent Variables or

  • Scope Variables

In the Research Questions Applet the

  • TOPIC (Independent Variable or IV),

  • ISSUE (Dependent Variable or DV) and

  • SCOPE (Scope Variable or SV) are displayed.

In the menu on the screen, clicking on the TOPIC displays all IVs that are available to the researcher.

The researcher chooses an appropriate TOPIC and similarly, ISSUE and SCOPE .

The researcher can fill in connecting texts in the TEXT boxes to make a meaningful sentence.

The MODIFIER is the change or relationship to be tested.

Following this method, a full Research Question is now synthesized.

2. Hypothesis Test

The researcher can then choose the statistical test based on the

  • MODIFIER = Decrease, and type of

  • SAMPLE = 1 Independent Sample, and all available tests are shown

Unlike any other software, AsterWrite provides enormous help:

First it provides indication of what the researcher is about to do.

Second it provides information of the test, the assumptions, the hypothesis and the test statistic.

Third, it provides information of the test design type.

Fourth, it provides information of the test method and formulae.

3. Statistical Test

With these information the researcher chooses the correct test.

Once data is entered, or imported from an Excel file, AsterWrite completes the analysis.

Here is a sample output from AsterWrite showing three cases:

  • Case 1 Ho: m is greater than or equal to µ

  • Case 2 Ho: m is equal to µ

  • Case 3 Ho: m is less than or equal to µ.

Depending on the {modifier} in the research question, AsterWrite determines the test pertinent to the hypothesis.

Thus, the hypothesis tests follows almost automatically from the research questions.

AsterWrite does the calculation and presents the graphs and the Conclusion.

Common tests are t-tests (1, 2 samples and Paired}, Proportions (1, 2 samples), Variance (1, 2 samples), Chi-squared, Test of Independence, Goodness of Fit, etc.

There are many other statistical tests available in AsterWrite.

Most common parametric and non-parametric tests are available.

More tests are added regularly.

AsterWrite has templates for Mediation and Moderation studies together with homogeneity and analysis of covariance.

Principal Component Analysis, Factor Analysis and Multiple regression are all features of AsterWrite.

Design of Experiments is also built into AsterWrite.

There is a full suite of commonly used statistical tests linked to the research questions.
