Growers took red and yellow carrots to create the orange root, just like using a paint box. Before then, carrots were purple, red, white, green, yellow, or black. Carrots are readily available in five main colors in the stores these days: orange, red, purple, white, and yellow. Each color has a different health benefit.
A pilot study, pilot project or pilot experiment is a small scale preliminary study conducted in order to evaluate feasibility, time, cost, adverse events, and effect size (statistical variability) in an attempt to predict an appropriate sample size and improve upon the study design prior to performance of a full-scale research project.
The amount of time to be scheduled for the individual phases depends to a large extent on the scope of the project, but in most cases more than a year is likely to be required. Implementing a serialization project â especially in the case of pilot lines â can sometimes take as long as 15 to 24 months.
