Introduction
The purpose of the paper is to prepare a questionnaire and give a survey report, speculate
on the reliability of the collected data, methods to validate the collected data, and challenges of
using online questionnaire. Also, questionnaires are for people to find out things with anonymity
so that they can “pool” the results to figure out what needs changed or what they can better
improve on. Also, using a survey site allows for the filtration of those who are being honest and
those who are just giving bad reviews based on biased opinions or personal inconsistencies
between the entity and themselves.
Aspects of creating and conducting an online survey
There are many aspects of creating and conduction an online survey. Sometimes, it is
best to first figure out what the surveys purpose is. For example, surveys about college
professors should not be aimed directly at the professor, but rater, aimed toward the class. Other
things to consider is the length of the survey. This is more dependent on how you are survey a
certain thing. For example, surveying a teacher for a primary school many only need to consist
of thins like “was the teacher nice? Did the teacher make sure you were learning?” or was it
easy to learn what the teacher was teaching. On the other hand, when doing a survey on say a
doctor it is more about the doctor’s knowledge, bedside manner, attention to the needs or
concerns of the patient. As show in the example surveys have a wide verity of uses. With all the
things that need to be considered when conducting a survey, one thing should always remain and
that is the pool of people who are taking the survey. If a doctor is presenting a survey to a group
, of un-educated patients, the survey should be conducted in a manner where the un-educated
people can understand it.
Reliability of the collected data
Validity is what makes a survey reliable. There are many types of validity. Starting with
the content. Content in the survey is once aspect that leads to the reliability of a survey. The
broader the questions are, the less validity it has. According to Relevant Insights, surveys must
have both validity and reliability (1). Validity comes from asking the right question and
reliability comes from how the questions are asked. There are three different types of validity in
surveys. The first is content validity. Content validity is making the question are related to the
topic of the survey itself. The second is internal validity. Internal validity is making sure that the
questions not only have content validity, but also have the desired resulted information. Last is
external validity. External validity is comparing outside things of the same nature. For example,
Alabama football records must be surveyed among other teams.
Methods of validation
Validation of a survey comes from two places. According to mTab, the six steps requrid
to validate a survey are as follows: establish face validity, pilot test, clean collected data, use
principal components analysis, check internal consistency, and revise survey (2). Face validity is
having someone from each side of the survey review it. The piolet test is next. This is for just a
few of the group you intend to survey. It would be like a tenth of the group. After the piolet test
comes the data collection. This is the interpretation of the data. The principal components
analysis is what identifies the measurement of the question in the survey. Internal consistency is
next. Revising is the nest and final step. This step is the survey reapplied with all the
information collected form the previous steps.
