A researcher designs his questionnaire in such a way that respondents can communicate the intensity with which they like or dislike a product by circling an appropriate number from the response options that go from 1 to 7 (where 1 is "strongly disagree" and 7 is for "strongly agree"). These numbers (1 to 7) are commonly referred to as:

First let's define a Likert scale. A Likert scale is a psychometric scale that researchers tend to use when it comes to applying questionnaires to people.

When people respond to a Likert scale item, they specify their level of agreement or disagreement on a symmetric agree-disagree scale for a series of statements.

For example, if we were to have a scale comprised of 5 agree-disagree levels, they could be:

Strongly disagree
Disagree
Neither agree nor disagree
Agree
Strongly agree

And people would have to choose for each item, how much they agree or disagree. Each of these numbers are referred to as "scale points"

In this example, the researcher designs his questionnaire in such a way that people who will answer will be able to communicate how much they like or dislike a product by circling a number. This is clearly a Likert scale questionnaire and therefore, each one of the numbers (1 to 7) is referred to as Scale points.
