The term scaling is applied to the attempts to measure the attitude objectively. Attitude is a resultant of number of external and internal factors. Depending upon the attitude to be measured, appropriate scales are designed. Scaling is a technique used for measuring qualitative responses of respondents such as those related to their feelings, perception, likes, dislikes, interests and preferences. Four types of scales are generally used for Marketing Research.
Metrics details. An Erratum to this article was published on 03 March The scale development process is critical to building knowledge in human and social sciences. The present paper aimed a to provide a systematic review of the published literature regarding current practices of the scale development process, b to assess the main limitations reported by the authors in these processes, and c to provide a set of recommendations for best practices in future scale development research. We evaluated studies published between and The analysis considered the three basic steps in scale development: item generation, theoretical analysis, and psychometric analysis.
Measurement is the numerical quantification of the attributes of an object or event, which can be used to compare with other objects or events. In natural sciences and engineering , measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures. Measurement is a cornerstone of trade , science , technology , and quantitative research in many disciplines. Historically, many measurement systems existed for the varied fields of human existence to facilitate comparisons in these fields. Often these were achieved by local agreements between trading partners or collaborators.
In statistics, there are four data measurement scales: nominal, ordinal, interval and ratio. Nominal scales are used for labeling variables, without any quantitative value. Notice that all of these scales are mutually exclusive no overlap and none of them have any numerical significance. Note : a sub-type of nominal scale with only two categories e. Take a look at the example below.

An attitude measurement survey is a study, on a properly drawn sample, of a specified population to find out what people in that population feel about a specified issue. This is possible when an attitude is conceptualised as measurable on a single scale. Such a scale may be nominal, ordinal or interval, in theory, although most are constructed and used as though they were interval scales even when they are ordinal. There are several established procedures for attitude scaling including the Thurstone, Likert, and Guttman methods.
Scales of measurement in research and statistics are the different ways in which variables are defined and grouped into different categories. Sometimes called the level of measurement, it describes the nature of the values assigned to the variables in a data set. The term scale of measurement is derived from two keywords in statistics, namely; measurement and scale. Measurement is the process of recording observations collected as part of a research. Scaling, on the other hand, is the assignment of objects to numbers or semantics. These two words merged together refers to the relationship among the assigned objects and the recorded observations. A measurement scale is used to qualify or quantify data variables in statistics.
Measurement scale , in statistical analysis , the type of information provided by numbers. Each of the four scales i. Measurement refers to the assignment of numbers in a meaningful way, and understanding measurement scales is important to interpreting the numbers assigned to people, objects, and events. Gender is an example of a nominal measurement in which a number e.

But it is not easy to measure properties like motivation to succeed, ability to stand stress and the like. One cannot do much with the numbers involved. Ex: To code gender, Male assigned code 1, female 2. Nominal data are numerical in name only, because they do not share any of the properties of the numbers we deal in ordinary arithmetic.
Definition: Scaling is the procedure of measuring and assigning the objects to the numbers according to the specified rules. In other words, the process of locating the measured objects on the continuum, a continuous sequence of numbers to which the objects are assigned is called as scaling. Scaling is considered as the extension of measurement. What is Measurement?
Definition : Scaling technique is a method of placing respondents in continuation of gradual change in the pre-assigned values, symbols or numbers based on the features of a particular object as per the defined rules. All the scaling techniques are based on four pillars, i. The marketing research is highly dependable upon the scaling techniques, without which no market analysis can be performed. The researchers have identified many scaling techniques; today, we will discuss some of the most common scales used by business organizations, researchers, economists, experts, etc. Let us now study each of these methods in-depth below:. Nominal scales are adopted for non-quantitative containing no numerical implication labelling variables which are unique and different from one another. For example , At Amazon.

- А теперь, - продолжал он, перейдя на шепот, - чем я могу вам помочь. Беккер тоже понизил голос: - Мне нужно поговорить с одной из сопровождающих, которая, по-видимому, приглашена сегодня к вам на обед. Ее зовут Росио. Консьерж шумно выдохнул, словно сбросив с плеч тяжесть. - А-а, Росио - прелестное создание. - Мне нужно немедленно ее увидеть. - Но, сеньор, она занята с клиентом.
Дверь высотой в шесть метров закрылась с гулким стуком, и Беккер оказался заперт в Божьем доме. Он закрыл глаза и постарался сползти на скамье как можно ниже: он единственный в церкви был не в черном. Откуда-то донеслись звуки песнопения. В задней части церкви между скамьями продвигался человек, стараясь держаться в тени.
Шифр!. Сьюзан смотрела на эти буквы, и они расплывались перед ее слезящимися глазами. Под вертикальной панелью она заметила еще одну с пятью пустыми кнопками. Шифр из пяти букв, сказала она себе и сразу же поняла, каковы ее шансы его угадать: двадцать шесть в пятой степени, 11 881 376 вариантов. По одной секунде на вариант - получается девятнадцать недель… Когда она, задыхаясь от дыма, лежала на полу у дверцы лифта, ей вдруг вспомнились страстные слова коммандера: Я люблю тебя, Сьюзан.
Он сел в кровати. - Нуда, конечно… С удовольствием. Беккер достал блокнот.
