How many questionnaires is enough for a dissertation?

Most recent answer As a rule of thumb, one should use multiplier of minimum five to determine the sample size i.e. if you are having 30 questions in your questionnaire multiply it with 5 = 150 responses (minimum).

What are the different types of scales used in questionnaires?

When designing surveys, there tend to be three different models for survey response scales: Dichotomous; Rating scales; Semantic differential scales….The three most common rating scales are:110;17;15 (or Likert scale).

How many types of scales are used in social research?

Based on the four generic types of scales discussed above, we can create specific rating scales for social science research. Common rating scales include binary, Likert, semantic differential, or Guttman scales. Other less common scales are not discussed here.

What are the 5 types of measurements?

Types of data measurement scales: nominal, ordinal, interval, and ratio.

What are the 4 types of scales?

The Four Scales of Measurement. Data can be classified as being on one of four scales: nominal, ordinal, interval or ratio. Each level of measurement has some important properties that are useful to know.

What are the two types of scales?

There are two main types of measurement scales, namely; comparative scales and non-comparative scales.

What are 3 types of scales?

There are three main ways that scale is indicated on a map: graphic (or bar), verbal, and representative fraction (RF).

What is a scale variable?

A scale variable, for example, covers a variety of statistical and survey information that can be precisely measured via a numeric value. A nominal variable is a type of scale variable that codes for something that is not quantifiable, such as color, gender or product type.

What are the 4 types of data?

Table of Contents: Introduction to Data Types. Categorical Data (Nominal, Ordinal) Numerical Data (Discrete, Continuous, Interval, Ratio)

What is an example of a scale variable?

In behavioral science, a scale variable is defined in a different way. A variable from this type of distribution is called a scale variable. Scale scores (or, more simply, a score) are a result of these distributions. For example, an IQ score or a score on a depression scale are both derived from the above definition.

How do you classify a variable?

Classifying variables can be somewhat contentious. Standard statistical textbooks will state that variables can be broadly classified as categorical or continuous. Categorical variables can be further categorised into nominal (e.g. ethnic group), ordinal (e.g. tumour staging) and dichotomous (e.g. sex).

What type of variable is birth month?

Since there are exactly 12 possible birth months, it is discrete, and can be categorical. It is qualitative, as it describes an attribute or quality of the subject, namely the birth month.

Is Date qualitative or quantitative?

They are ordinal, as one date is bigger than the date before it. It is also quantitative as it can added, subtracted…etc.

Is birth nominal or ordinal?

An ordinal-scale variable has values that can be ranked but are not necessarily evenly spaced, such as stage of cancer (see Table 2.3). An interval-scale variable is measured on a scale of equally spaced units, but without a true zero point, such as date of birth.

Is age categorical or quantitative?

In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values. It also makes sense to think about it in numerical form; that is, a person can be 18 years old or 80 years old.

Is brand categorical or quantitative?

Quantitative variables are any variables where the data represent amounts (e.g. height, weight, or age). Categorical variables are any variables where the data represent groups. This includes rankings (e.g. finishing places in a race), classifications (e.g. brands of cereal), and binary outcomes (e.g. coin flips).

Is hours of sleep quantitative or categorical?

Amount of sleep is a variable. 3, 5, 9 hours of sleep are different values for that variable. Variables can be continuous or discrete.
