Your study, and your stats.
The inside joke
Statistical power below 0.8 (1−β) means your study probably can't find the effect.

Fit
Relaxed, roomy unisex fit. Because it's garment-dyed for that soft, washed color, it runs about a half to a full size smaller than a standard tee. So if you're between sizes, or you want the classic oversized look, size up.
Size chart
| Size | Chest (width, laid flat) | Length (shoulder to hem) |
|---|---|---|
| S | 18 | 28 |
| M | 20 | 29 |
| L | 22 | 30 |
| XL | 24 | 31 |
| 2XL | 26 | 32 |
| 3XL | 28 | 33 |
Width is measured across the chest one inch below the armhole, laid flat. Relaxed unisex fit; because it's garment-dyed for that soft, washed color, it runs about half a size to a full size small, so size up if you're between sizes or want it oversized. Measurements vary slightly from batch to batch.
