Question

Which of the following characteristics of experiments are also characteristics of surveys?

A. The study involves one or more treatment groups and a control group.
B. Replication with different groups of subjects can improve the reliability of the study.
C. Data are gathered during the course of the study.
D. The study compares two or more treatments (possibly including ""no treatment"").
E Statistical analysis is applied to the results of the study.

Answer 1

The characteristics common to both experiments and surveys include the capability for replication to enhance reliability, the collection of data during the study, and the use of statistical analysis on study results.

Step-by-step explanation:

The student has inquired about the characteristics that experiments and surveys have in common. Among the listed options, the following characteristics can be identified as shared by both methods:

• Replication with different groups of subjects can improve the reliability of the study.
• Data are gathered during the course of the study.
• Statistical analysis is applied to the results of the study.

While both experiments and surveys can have control and treatment groups and can involve the comparison of treatments, these are more directly associated with experimental design, where variables are actively manipulated. Surveys, being a type of observational study, typically do not involve this kind of manipulation, but they often rely on replication and statistical analysis to ensure the reliability and validity of their findings.
