The answer is; to reduce statistical error and ensure a real representation the entire population.
The size of the sample size determines the precision or confidence level of the applied statistics. A proper sample size is able to capture the variability and uncertainties of the larger population and therefore estimate the larger population with good confidence levels.
Saturated fats are solid at room temperature, while unsaturated fats are liquid at room temperature. This is because saturated and unsaturated fats differ in their chemical structures.
Saturated fats have no double bonds between the molecules , which means there are no gaps and the fat is saturated with hydrogen molecules. Unsaturated fats have double bonds, which break up the chain of hydrogen molecules and create gaps, allowing the fats to liquefy at room temperature.
Saturated fats are found mainly in animal food such as meat and dairy products, while unsaturated fats are found in plant food and fish.
