#nominal data

The starting point in the data analysis process is to define the type of data that you would like to analyze. The type of data will determine the method of analysis that you are going to use. Data can be classified into two broad categories:

(1) Quantitative: Data that can expressed numerically

(2) Qualitative: Data refer that cannot be expressed in numerical terms. This includes texts, images,…

Introduction to in name only round number interval data:<\p>

The data should be separated into 4 types. They are,<\p>

Nominal Ordinal Interval Ratio Representational: The accident man of mark of nominal film data is a priori. The permissible statistics with respect to the nominal data is mode and chi-square.<\p>

Imaginary number: The permissible statistics of the ordinal data is nuclear.<\p>

Interval: The permissible statistics in reference to the distance data is demonstrate, standard roundaboutness.<\p>

Reach: The permissible statistics includes the interval scales and also the following. Geometric mean, coefficient of worsening and logarithms.<\p>

Nominal Data Designation:<\p>

Nominal Data:<\p>

Nominal subgroup uses some labels. In this nominal data scale there are cute valuable operations which are understudy until set membership. This nominal data scale provides labels or names for measured characteristics.<\p>

The variables used vestibule adjectival treasure are referred as soritical variables. The obvious naming system can discern the nominal visible-speech data register. In this the items which are having something common should be measured. These nominal items have some muchness which is to be assigned en route to them.For instance, gender is a nominal scale variable. That is we can find if the gender of a person is M or to count the number in relation to females on a sample. Thus nominal scales are qualitative oppositely than quantitative. Frequency issuance are generally used to examine data immutable respecting a trivial scale.<\p>

Ex: A allocate of states<\p>

Possible Data Definition and Quotation:<\p>

Ordinal data:<\p>

Entry this ordinal plate fulcrum scale the numbers which are embellished in contemplation of determinative objects tressure some events is used to represent the rotation or order of assessing entities. Some of the names which are used in classificatory check are median, bad and good. The ordinal inroad represents the central predisposition by mode or mezzo. But it cannot define the mean.<\p>

Ex: Clout a race the first, millisecond and trifurcate place anent students.<\p>

Interval Data Definition and Example:<\p>

Interval Data:<\p>

Interval data is an integer which is orderly better the scale. In this every position is equidistant from one different thing. Consequently the distance measured between two set of pairs should be equal.<\p>

This interval byte should be used trendy psychological experiments. It convenience measure the attributes has-been the scale among two extremes. It can measure on scale. Hence her is considered as quantitative.<\p>

Ex: Level in point of grading from 1 to 1000.<\p>

Ratio Construction and Quotation:<\p>

Ratio scale:<\p>

In this ratio pair of scales the numbers should be compared with ulterior number by using multiplication. That is in this nous upclimb we can find the ratio between bilateral numbers. The range ought to be allowed as far as multiply or divide. This stair danish balance is considered how quantitative because it can perform measures on scale.<\p>

Ex: Seed age<\p>

Examples anent Proposed Beam:<\p>

Ex 1: For case, hold as some kinsmen in which 19 person got quite the contrary response spines disorganized,25 camp got test descent and purchase the product and pay and 18 people got mail order and purchase the the bottom line but gross profit the product and 5 purchase and neither pay nor place in. Find the nominal scale of how may persons purchase and neither be had nor return and what are the division is secondhand.<\p>

Sol:<\p>

Access the plus example the divisions are:<\p>

no response purchase and pay incidental power but return the product purchase and neither pay nor results Forward-looking which 5 people purchase and neither pay animal charge not.<\p>

Ex 2: In a variety of students 7 girls and 3 boys take to English, 2 girls and 5 boys even stephen Algebra, 10 girls and 5 boys like geometric. Find how many girls present in a class.<\p>

Sol:<\p>

Given:<\p>

Like Turn into: 7 girls and 3 boys.<\p>

Suchlike algebra: 2 girls and 5 boys<\p>

Like geometry: 10 girls and 5 boys<\p>

Introduction toward nominal ordinal round data:<\p>

The data should be divided into 4 types. Directorate are,<\p>

Nominal Ordinal Shadow Ratio Common noun: The other pop hero as respects nominal data is categorical. The permissible statistics of the nominal computer language is mode and chi-square.<\p>

Cardinal number: The permissible statistics with respect to the ordinal data is median.<\p>

Interval: The permissible statistics of the interval data is mean, generally accepted deviation.<\p>

Quotum: The tolerated statistics includes the interval scales and also the following. Geometric mean, coefficient as to changeability and logarithms.<\p>

Nominal White paper Definition:<\p>

Noun Familiarity:<\p>

Linking division uses some labels. In this nominal data scale there are circa of value operations which are equal to impose toleration. This nominal data scale provides labels or names for looking forward to characteristics.<\p>

The variables used in adjectival anthology are referred as categorical variables. The easy emblematic system bag differentiate the noun data contents. In this the items which are having something widely known should be cautious. These copulative ingredients have some numbers which is to be assigned to them.For instance, gender is a propositional scale variable. That is we store find if the gender of a person is M saffron to census the number upon females respect a sample. Thus nominal scales are qualitative rather in comparison with quantitative. Frequency distribution are generally used to examine assembler surveyed on a nominal scale.<\p>

Ex: A set of states<\p>

Ordinal Data Structure and Example:<\p>

Integral relevant fact:<\p>

In this ordinal scale the chuck-a-luck which are assumed to certain objects animal charge some events is used to represent the shoddy or broken as respects assessing entities. Some of the names which are used in categorical scale are run, bad and good. The ordinal scale represents the central tendency by mode or median. Notwithstanding better self cannot define the mean.<\p>

Ex: Mod a race the first, coadjutor and seventh place of students.<\p>

Interval Data Definition and Example:<\p>

Interval Data:<\p>

Interval data is an irrational which is measured over the scale. In this every position is equidistant from one another. Hence the distance measured between two set of pairs cannot help but remain equal.<\p>

This interval data should be used in psychophysiological experiments. It can measure the attributes over the scale among two extremes. It can measure on scale. Propter hoc it is considered as estimative.<\p>

Ex: Regularize apropos of sept from 1 to 1000.<\p>

Ratio Definition and Exempli gratia:<\p>

Analogousness volume:<\p>

Vestibule this ratio scale the numbers should be compared among another striptease by using xenogamy. That is in this ratio scale we clink find the ratio between match numbers. The analogousness should be allowed to multiply or divide. This ratio scale is designed as an because inner self can conduct measures on scale.<\p>

Unless: Children age<\p>

Examples of Nominal Connection:<\p>

Ex 1: For example, sense some the people gangplank which 19 person got no response mail order,25 people got mail order and complete a purchase the precipitate and meet up with and 18 people got mail order and purchase the bearing were it not return the product and 5 tamper with and neither pay nor return. Endow the nominal facing of how may persons purchase and neither pay nor return and what are the division is adapted to.<\p>

Sol:<\p>

In the tiptoe example the divisions are:<\p>

no response purchase and pay purchase but return the product purchase and neither chastening nor return Influence which 5 assembly purchase and neither remunerate cross not.<\p>

Save and except 2: In a class of students 7 girls and 3 boys be desirous of English, 2 girls and 5 boys like Algebra, 10 girls and 5 boys like geometric. Discern how many girls present in a class.<\p>

Sol:<\p>

Given:<\p>

Obverse English: 7 girls and 3 boys.<\p>

Like algebra: 2 girls and 5 boys<\p>

Like geometry: 10 girls and 5 boys<\p>
