Singing Study Comments
Fragment of a discussion from Course talk:STAT 550
- It is suspicious that the control group was eliminated altogether. Choosing to eliminate them because they did not support the hypothesis would result biased results.
- They tested several hypotheses at once, but focused on the (possibly false) positive results.
- Of the low-functioning patients, only those whose relatives were involved enough to return the consent form were included. This is not a representative population.
- Choosing to sing is associated with having a high-functioning (good) day. High-functioning days leads to higher scores on the tests. Therefore, the choosing to sing, not the singing itself, could be the factor influencing the scores.
