Chapter 1, Problem 1LTB

Add labels to the figure that follows, which illustrates the characteristics of research participants in control versus experimental groups.

Summary Introduction

To fill up:

The figure that gives the features of research participants in between the control and experiments groups of a scientific hypothesis:

1. Control group (a) experiencing the early cold symptoms. (b) ____________ and received (c) _________ tea.
2. Experimental group (a) __________, (b) sought treatment from clinic, and (c) received echinacea tea.

Introduction:

A scientific control experiment can be defined as an observation or experiment which is designed to decrease the effects of the variable other than the self-governing variable. This raises the reliability of the results usually through an evaluation between the control and other measurements.

Explanation of Solution

An experimental group can be defined as the group which performs an experiment which receives the variable being verified. One variable is confirmed at a time. The experimental group is associated with a control group. Control group does not receive the test variable. Thus, the experimental groups are used to identify the answers in an experiment.

The table gives the features of research participants in between the control and experiments groups:

1. Control Group	2. Experimental Group
experiencing the early cold symptoms	experiencing the early cold symptoms
sought treatment from clinic	sought treatment from clinic
Received placebo tea	received echinacea tea

The given table shows a study that describes and support the hypothesis. In this hypothesis, the echinacea tea decreases the severity of colds. Using some placebo tea makes only a single reliable difference between the individuals in the two groups. In the echinacea tea experiment, the severity of cold was lower in the experimental group than those who have received a placebo.

Though, it is very rare that a single experiment will remove all the probable and different explanations. This makes the scientific community to admit a hypothesis beyond a real doubt.

Conclusion

Hence, the table gives the features of research participants in between the control and experiments groups of a scientific hypothesis:

1. Control group (a) experiencing the early cold symptoms, (b) sought treatment from clinic and received (c) placebo tea.
2. Experimental group (a) experiencing the early cold symptoms, (b) sought treatment from clinic, and (c) received echinacea tea.
