Question

A researcher measured the shoe size and reading ability of a large group of children. She found that, as shoe size increases, so does reading ability. What does her analysis show? There is no correlation between shoe size and reading ability. There is a correlation between shoe size and reading ability. There may or may not be causation. Further studies would have to be done to determine this. There is a correlation between shoe size and reading ability. There is probably also causation. This is because there is an increase in reading ability with an increase in shoe size.

Answer 1

The researcher's finding shows a correlation between shoe size and reading ability. However, correlation does not imply causation, and further studies are needed to determine if there is a cause-and-effect relationship.

Step-by-step explanation:

The researcher's analysis indicates that there is a correlation between shoe size and reading ability since as one variable increases, so does the other. However, it's important to note that while a correlation can suggest a relationship between two variables, it does not establish causation. In other words, even though the data points to a correlation, this does not mean that an increase in shoe size causes an improvement in reading ability. There could be a confounding variable at play, such as age, where older children might have both larger shoe sizes and better reading skills due to their development and education. Therefore, further studies would be required to determine whether a causal relationship exists.

When evaluating the relationship between two variables, such as in the scenario provided, where positive correlation is mentioned between weight and height, it is essential to remember that this does not necessarily indicate that one factor causes the other. Correlation and causation are different concepts, and correlational research has its limitations. It cannot definitively prove that one variable is the cause of changes in the other without further, comprehensive study.

Answer 2

There is a correlation between shoe size and reading ability. There may or may not be causation. Further studies would have to be done to determine this.

Step-by-step explanation:

Correlation: In research, the term "correlation" is described as a specific relationship that tends to exist between two or more than two variables, for example, crime & ice-cream consumption, yet this relationship doesn't imply "cause-and-effect" necessarily. Therefore, when two different variables are being correlated, it means that if one variable will change then the other will change as well. correlation is negative and positive types.

In the question above, the given statement represents a positive correlation as both the things are going in the same direction i.e., increasing.
