### How to Calculate the Ratio Between Two Numbers | Sciencing

Sample Size Calculator Terms: The confidence level tells you how sure you can be. It is expressed as a percentage and represents how often the true percentage of the population who would pick an answer lies within the confidence interval. The wider the confidence interval you are willing to accept, the more certain you can be that the whole population answers would be within that range.

There are three factors that determine the size of the confidence interval for a given confidence level: Sample size Population size Sample Size The larger your sample size, the more sure you can be that their answers truly reflect the population.

This indicates that for a given confidence level, the larger your sample size, the smaller your confidence interval. However, the relationship is not linear i. Percentage Your accuracy also depends on the percentage of your sample that picks a particular answer.

It is easier to be sure of extreme answers than of middle-of-the-road ones. You should also use this percentage if you want to determine a general level of accuracy for a sample you already have. To determine the confidence interval for a specific answer your sample has given, you can use the percentage picking that answer and get a smaller interval. Population Size How many people are there in the group your sample represents?

The numbers may represent two parts of a whole, or one of the numbers may represent a part of a whole while the other number represents the whole itself.

Expressing a Ratio Mathematicians and scientists use one of three conventions to express a ratio. Suppose you have two numbers A and B.

You can express the ratio between them as: Sciencing Video Vault As an example, consider a grade school class which has 32 students, 17 of whom are girls and 15 of which are boys. The ratio of girls to boys can be written as The classroom has 32 students, so the ratio of girls to the total number of students is When comparing part of a whole to the whole, you can convert the ratio to a percentage by expressing it in fractional form, dividing the antecedent by the consequent and multiplying by In terms of percentages, the ratio of girls to boys is Scaling a Ratio You scale a ratio by multiplying both the antecedent and consequent by the same number.

In the above example, we scaled the ratio by multiplying by to give us percentages, which are often more useful than raw numbers.

Cooks often need to scale ratios to adapt recipes for different numbers of people. For example, a recipe intended to feed 4 people calls for 2 cups of soup mix to be added to 6 cups of water.
