Percentages, Fractions, and Decimal Values

Percentages are defined as a fraction or portion of a whole. Generally percentages deal with an amount out of one hundred but can be used in sales, economics, and science. If you've walked into any store you're sure to find something marked a certain percent off. Fractions are not whole numbers with a numerator over a denominator. Usually the numerator and denominator are expressed as integers. There are four types of fractions: simple fractions, complex fractions, mixed fractions, and improper fractions. Decimals are also not integers. They are expressed often like 0.34 and are often rounded off since some go for too long. Both decimals and fractions are also used to convert to percentages.

Why does repeating increases reliability?

Repeating an experiment or observation increases reliability by reducing the impact of random errors and variability, allowing for more accurate and consistent results. Each repetition helps to confirm that the findings are not due to chance and provides a larger dataset for analysis. This enhances the credibility of the results and strengthens the overall conclusions drawn from the research. Additionally, repeated measures can help identify patterns or trends that may not be visible in a single trial.
