Which of the following characteristics of experiments are not also characteristics of surveys?

check all that apply.

a.
data are gathered during the course of the study.

b.
two or more treatments are compared in the study (possibly including "no treatment").

c.
one or more treatment groups and a control group are included in the study.

d.
the results of the study are analyzed statistically.

e.
replication with other groups of subjects can improve the reliability of the study.

The correct answer is option E and option C

Step-by-step explanation: From the question, all the option are characteristics of an experimental study, while some are as well characteristics of a survey study. We now have to identify the options that are not characteristics of a survey study.

Survey study is an observational study that is carried out to discover the characteristics of a sample group under a specific criteria and to compare the characteristics of this sample groups.

Replication with other groups of subjects cannot improve the reliability of a survey study, because two different survey study using a different samples or a different location will not have the same characteristics, and the result gotten from each sample can only be used to define that sample or the location of that sample.

It is not a prerequisite that one or more treatment groups and a control group should be included in a survey study. Because a survey group can also observe samples in their natural cause, without applying any force or treatment to alter them.

Data are gathered during a survey because we record our results and observations. A survey research is all about gathering data from either a treatment group or non treatment group, to compare with another data, and knowing the relationship between the characteristics of the sample. The result of the samples of a survey study are compared and analysed using statistics which includes mean, mode, range, bar chart, graph, histograms, and many more.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
