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.

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.

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.

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.
