Add labels to the figure that follows, which illustrates the characteristics of research participants in control versus experimental groups.
To fill up:
The figure that gives the features of research participants in between the control and experiments groups of a scientific hypothesis:
- Control group (a) experiencing the early cold symptoms. (b) ____________ and received (c) _________ tea.
- 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.
Hence, the table gives the features of research participants in between the control and experiments groups of a scientific hypothesis:
- Control group (a) experiencing the early cold symptoms, (b) sought treatment from clinic and received (c) placebo tea.
- Experimental group (a) experiencing the early cold symptoms, (b) sought treatment from clinic, and (c) received echinacea tea.

RCTs can be expensive, which can make it difficult if funding is limited b. RCTs can be time-consuming, and it may take months and sometimes years to obtain final results c. For certain research questions and/or certain types of exposure variables, it may not be ethical to conduct an RCT d. RCTs are less valid than observational analytical study designsarrow_forward

The retailer is trying to decide what level of lighting and what temperature they should maintain in its stores to maximize sales. Identify the independent variable and dependent variable in this case. How would the independent variable be manipulated to measure differences across the dependent variable. Include details about the experimental design including the experimental groups.arrow_forwardThe 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.arrow_forward
