Determine whether the description below corresponds to an observational study or an experiment. in a study sponsored by a company, 12,668 people were asked what contributes most to their anxiety commaanxiety, and 69% of the respondents said that it was their partner. is the study described above an observational study or an experiment?

The study described above is an observational study.

Explanation:

The main difference between an observational study and an exepriment, is that in an experiment there is a manipulation of one or more variables, this usually happens in a controled environment. In an observational study, the conditions of the research subjects are not meant to be altered but only observed, surveys and interviews are common research techinques used for this purpose.

The example above is describing an observational study since there is no manipulation of variables, only a survey that aimes to understand the factors that influence the dependent variable, that in this case is anxiety.

there are treatment options for depression (mdd) that may work for you. one way of treating depression may be to affect the levels of certain chemicals that brain cells use to communicate, called neurotransmitters. scientists believe that certain neurotransmitters may be out of balance in depression.

although the exact way depression medications shown to ease overall depression symptoms in some people work is unknown, scientists think that some medications work by affecting the levels of a neurotransmitter called serotonin in the brain. other treatments work by affecting the levels of other neurotransmitters like norepinephrine or dopamine.

after balancing the chemical equation, what are the coefficients for these compounds?
