The Likert scale, introduced by Rensis Likert in 1932, is a widely used psychometric scale for measuring attitudes or opinions through fixed-choice responses. This one-dimensional scaling technique allows respondents to express varying levels of agreement or disagreement, facilitating data collection and analysis in surveys. However, its implementation may lead to biases, with participants potentially influenced by previous questions or their feelings towards the surveyor.

2.  The original idea for the likert scale is found in
Rensis Likert’s 1932 article in Archive of
psychology titled “ A technique for the
measurement of Attitudes”.
 Likert-type or frequency scales use fixed
choice response formats and are designed to
measure attitudes or opinions

3. • It is a psychometric scale commonly
involved in research that employs
questionnaires.
• It is the most widely used approach to
scaling responses in survey research.
• Likert scales are a non-comparative scaling
technique and are one-dimensional in
nature.
• When responding to a Likert questionnaire
item respondents specify their level of
agreement or disagreement on a symmetric
agree-disagree scale for a series of
statements.

5.  I believe that ecological questions are the
most important issues facing human beings
today.
Strongly agree / agree / don’t know /
disagree / strongly disagree
Each of the five (or seven) responses would
have a numerical value which would be used
to measure the attitude under investigation.

6.  We can use it to get an overall measurement
of a particular topic, opinion, or experience
and also collect specific data on contributing
factors.
 Choose a particular scale (3 point, 5 point, 7
point, etc) and use it as your standard to cut
down on potential confusion and fatigue.
This will also allow for comparisons within
and between your data sets.

7.  Likert Scale questions use psychometric
testing to measure beliefs, attitudes and
opinion.
 Working with quantitative data, it is easy to
draw conclusions, reports, results and graphs
from the responses.
 Likert Scale questions use a scale, & people
are not forced to express an either-or
opinion, rather it allows them to be neutral.
 It is very easy and quick type of survey and it
can be sent out through all modes of
communication, including even text
messages.

8.  They are uni-dimensional, because they only
give a certain amount of choices.
 Previous questions will have influenced
responses to any further questions that have
been asked.
 Participants may not be completely honest -
which may be intentional or unintentional.

9.  Participants may base answers on feelings
toward surveyor or subject.
 Scale requires a great deal of decision-
making.
 can take a long time to analyze the data
