The key word that designates multiplication or division is “each”. “Each” indicates that the groups being combined or split up need to be equal in size. Other words like “total”, “area”, “in all”, and “altogether” can designate multiplication or division.

## What you should do first when given a word problem to solve?

The first step to solving a math word problem is to read the problem in its entirety to understand what you are being asked to solve. After you read it, you can decide the most relevant aspects of the problem that need to be solved and what aspects are not relevant to solving the problem.

## What is the example of statistics?

A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic.

## What does statistical analysis include?

Statistical analysis is the collection and interpretation of data in order to uncover patterns and trends. It is a component of data analytics. In the context of business intelligence (BI), statistical analysis involves collecting and scrutinizing every data sample in a set of items from which samples can be drawn.

## What are the five types of statistical analysis used by researchers?

It all comes down to using the right methods for statistical analysis, which is how we process and collect samples of data to uncover patterns and trends. For this analysis, there are five to choose from: mean, standard deviation, regression, hypothesis testing, and sample size determination.
