Changes of this scale would lead me to question the methodology. There may well be some major trends at work, but it seems tremendously unlikely they are at this order of magnitude.
- seanmcdirmid 13y agoThe oscillations mostly occur in languages with low market share, while the error of measurement is probably fairly constant as a percent regardless of how widely the language is used! Also...from the TFA: > based on thousands of data points we've collected by processing over 100,000+ coding tests and challenges by over 2,000+ employers. They are measuring what 2000+ employers decided to test, which seems to me could be quite noisy anyways. Take the study for what it is...its still useful, just not really universal in its conclusion.
- gtirloni 13y agoIt would be useful if we knew from where those 2000+ employers are. This could be a highly focused view of some niche area for all we know. In this regard, although TIOBE could have the same problem, it seems to use a greater number of different sources to compose their index.
- seanmcdirmid 13y agoI think they would have the same problem to a lesser degree if they sampled 20,000 employers. At the low end, you would still get a lot of fluctuation year-on-year because their simply are not enough data points.
