... High fiber diets: A study in 1970 claimed that a high fiber diet reduces polyps forming in the colon, being precursors of cancer. A study in 2000 with more analyzed individuals showed no such effect. The uncertainty in the first study was too large and not properly accounted for. This left people ea ...

... Example: to calculate kilometers to meters you would need to use the appropriate conversion factor. If 1000m = 1km then 1000m/1km would be your conversion factor. Problem: by turning 5 kilometers into meters the number should get bigger 5km x 1000m/1km = 5000m (the number went from 5 to 5000) Exampl ...
