- Always use syntax, so you have a record of what you are doing
- Keep your syntax nicely organized
- Use notes liberally in your syntax, in SPSS and STATA this means starting a line with *
- Organize syntax into sections, e.g.

Calculating a mean or a standard deviation is not something done all that often, given that you can only calculate such statistics with interval or ratio level variables and most such variables have too many values to put into a frequency table that will be informative beyond what raw data would look like.… Read More “Calculating a mean or standard deviation from a frequency table”

When doing social research, what we care about most are populations, but what we have access to are samples. Samples are subsets of a population that we use to make estimates about populations. For example, if I wanted to know about American attitudes about the president, I couldn’t just pick up the phone and call the 327+ million American people and say “hey, gurrrl, what do you think about the prez?”… Read More “Samples vs. Populations”
