The word survey is used to describe a method to collect or gather
information from a group of people (a population sample) in order to learn
about their opinions, attitudes, and personal information.
They are characterized by the standardized questions
used to collect data, which means that every person responds to the same
question. The size of the sample varies, and this depends on what it needs to
be used for.
This means that while some findings are made public,
others are kept as private.
Surveys are classified into three types:
First, by their dimension, which refers to the
size and type of the sample population (e.g. all the children in a country,
students in public schools, political leaders, or consumers of a particular
product or service). Second, they are classified by their method of
data collection (e.g. telephone surveys, mail surveys,
and interview surveys).
|
Third, they are classified by their content.
While some surveys focus on opinions and attitudes towards an issue (like
virtual communication or past traditions), others are related to factual
characteristics, behaviors, memories and so forth (e.g. study habits, eating
habits, traditions).
Finally, to show the results of a survey in a visual
way, we can use a pie graph or a bar chart. While a pie graph is a circle
divided into segments or slices to represent a proportion of the data, a bar
chart is a chart with rectangular bars that show the frequency of the results.
To interpret the information in a graph, we should
identify the purpose of the graph, recognize its variables and see the
relation between labels, colors and numbers by looking at its title.
