How to write a proper hypothesis

Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion Communicate Your Results Following the scientific methodwe come up with a question that we want to answer, we do some initial research, and then before we set out to answer the question by performing an experiment and observing what happens, we first clearly identify what we "think" will happen. We make an "educated guess. We set out to prove or disprove the hypothesis.

Use parentheses and white-space to make code readable. All code should include comments meaningful to others. Labbooks Our peers in the laboratory sciences maintain lab-books. These books indicate what they did to perform their experiments. We are not generally performing experiments.

But we have identical goals. We want to be able to retrieve a record of every step we have followed to produce a particular result. This means the lab-book should include the names of every file of commands you wrote, with a brief synopsis of what the file was intended to do.

The labbook should indicate which produced results worth noting. Oct 11, File: Analysis - this file does multinomial probits on our basic model. The results were used in Table 1 of the Midwest paper. It is a good idea to have a template that you follow for each Labbook entry, this encourages you to avoid getting careless in your entires.

The above template includes: It may seem superfluous to indicate what machine the file was executed on. But should you develop the habit of computing on several machines, or should you move from one machine to another in the course of a project, this information becomes invaluable in making sure you can locate all off your files.

It makes a lot of sense to have the labbook online. It can be in either a Wordperfect file, or a plain ascii text file, or whatever you are most comfortable writing in. First, it is easy to search for particular events if you remember names of them.

Second, it can be accessed by more than one researcher if you are doing joint-work. Maintain a labbook from the beginning of a project to the end. The labbook should contain all the information necessary to take a given piece of data-analysis, and trace back where all of the data came-from - including its original source and all recode steps.

So while there are many different sorts of entries you might want to keep in a labbook, and many different styles to keep them; the central point to keep in mind is that whatever style you choose meets this purpose.

And even if we do, modern software will keep a log for us of what we have done a fact that seems to escape many users of the software. The reason I am not a fan of interactive work has to do with the nature of the analysis we do.

The model we ultimately settle on was usually arrived at after several estimates testing many models. And this is appropriate, we ought to all be testing the robustness of our results to changes in model specification, changes in variable measurement, etc. By writing command files to perform estimates, and keeping each version, one has a record of all of this.

There is alot to be said for this technique; but it is a bit beyond the scope of this article. And each file should not do too much.

Indicate any datasets the file utilizes as input. Indicate any output files or dataset created. If the file utilizes a data-set; there should be a comment indicating the source of the data-set.

This could be either another file you have that produced the data; or it could be a description of a public-use data set. If it is a public-use dataset, include the date and version number. For example, the first nine lines of a command file might be: Feb 2, Author: This file does multinomial probits on our basic model.

You should treat the comments at the top of a file the way you would the notes on a table; they should allow the file to stand alone and be interpreted by anyone opening the file without access to other files.
