Introduction – Significance of Knowledge
“Knowledge is the brand new oil.” Right this moment knowledge is in every single place in each area. Whether or not you’re a knowledge scientist, marketer, businessman, knowledge analyst, researcher, or you’re in every other occupation, you must play or experiment with uncooked or structured knowledge. This knowledge is so vital for us that it turns into vital to deal with and retailer it correctly, with none error. Whereas engaged on these knowledge, you will need to know the sorts of knowledge to course of them and get the correct outcomes. There are two sorts of knowledge: Qualitative and Quantitative knowledge, that are additional categorized into:
The info is classed into 4 classes:
- Nominal knowledge.
- Ordinal knowledge.
- Discrete knowledge.
- Steady knowledge.
Now enterprise runs on knowledge, and most corporations use knowledge for his or her insights to create and launch campaigns, design strategies, launch services or check out various things. In accordance with a report, right now, at the very least 2.5 quintillion bytes of information are produced per day.

Forms of Knowledge
Qualitative or Categorical Knowledge
Qualitative or Categorical Knowledge is knowledge that may’t be measured or counted within the type of numbers. Most of these knowledge are sorted by class, not by quantity. That’s why it’s also often called Categorical Knowledge. These knowledge encompass audio, photographs, symbols, or textual content. The gender of an individual, i.e., male, feminine, or others, is qualitative knowledge.
Qualitative knowledge tells in regards to the notion of individuals. This knowledge helps market researchers perceive the shoppers’ tastes after which design their concepts and methods accordingly.
The opposite examples of qualitative knowledge are :
- What language do you communicate
- Favourite vacation vacation spot
- Opinion on one thing (agree, disagree, or impartial)
- Colours
The Qualitative knowledge are additional categorized into two components :
Nominal Knowledge
Nominal Knowledge is used to label variables with none order or quantitative worth. The colour of hair will be thought of nominal knowledge, as one shade can’t be in contrast with one other shade.
The identify “nominal” comes from the Latin identify “nomen,” which implies “identify.” With the assistance of nominal knowledge, we will’t do any numerical duties or can’t give any order to kind the information. These knowledge don’t have any significant order; their values are distributed into distinct classes.
Examples of Nominal Knowledge :
- Color of hair (Blonde, purple, Brown, Black, and so forth.)
- Marital standing (Single, Widowed, Married)
- Nationality (Indian, German, American)
- Gender (Male, Feminine, Others)
- Eye Coloration (Black, Brown, and so forth.)
Ordinal Knowledge
Ordinal knowledge have pure ordering the place a quantity is current in some sort of order by their place on the dimensions. These knowledge are used for statement like buyer satisfaction, happiness, and so forth., however we will’t do any arithmetical duties on them.
Ordinal knowledge is qualitative knowledge for which their values have some sort of relative place. These varieties of information will be thought of “in-between” qualitative and quantitative knowledge. The ordinal knowledge solely exhibits the sequences and can’t use for statistical evaluation. In comparison with nominal knowledge, ordinal knowledge have some sort of order that’s not current in nominal knowledge.
Examples of Ordinal Knowledge :
- When corporations ask for suggestions, expertise, or satisfaction on a scale of 1 to 10
- Letter grades within the examination (A, B, C, D, and so forth.)
- Rating of individuals in a contest (First, Second, Third, and so forth.)
- Financial Standing (Excessive, Medium, and Low)
- Schooling Stage (Greater, Secondary, Major)
Distinction between Nominal and Ordinal Knowledge
| Nominal Knowledge | Ordinal Knowledge |
| Nominal knowledge can’t be quantified, neither they’ve any intrinsic ordering | Ordinal knowledge offers some sort of sequential order by their place on the dimensions |
| Nominal knowledge is qualitative knowledge or categorical knowledge | Ordinal knowledge is claimed to be “in-between” qualitative knowledge and quantitative knowledge |
| They don’t present any quantitative worth, neither can we carry out any arithmetical operation | They supply sequence and might assign numbers to ordinal knowledge however can’t carry out the arithmetical operation |
| Nominal knowledge can’t be used to match with each other | Ordinal knowledge might help to match one merchandise with one other by rating or ordering |
| Examples: Eye shade, housing type, gender, hair shade, faith, marital standing, ethnicity, and so forth | Examples: Financial standing, buyer satisfaction, schooling degree, letter grades, and so forth |

Quantitative Knowledge
Quantitative knowledge will be expressed in numerical values, making it countable and together with statistical knowledge evaluation. These varieties of information are often known as Numerical knowledge. It solutions the questions like “how a lot,” “what number of,” and “how usually.” For instance, the worth of a cellphone, the pc’s ram, the peak or weight of an individual, and so forth., falls beneath quantitative knowledge.
Quantitative knowledge can be utilized for statistical manipulation. These knowledge will be represented on all kinds of graphs and charts, equivalent to bar graphs, histograms, scatter plots, boxplots, pie charts, line graphs, and so forth.
Examples of Quantitative Knowledge :
- Top or weight of an individual or object
- Room Temperature
- Scores and Marks (Ex: 59, 80, 60, and so forth.)
- Time
The Quantitative knowledge are additional categorized into two components :
Discrete Knowledge
The time period discrete means distinct or separate. The discrete knowledge comprise the values that fall beneath integers or entire numbers. The whole variety of college students in a category is an instance of discrete knowledge. These knowledge can’t be damaged into decimal or fraction values.
The discrete knowledge are countable and have finite values; their subdivision shouldn’t be doable. These knowledge are represented primarily by a bar graph, quantity line, or frequency desk.
Examples of Discrete Knowledge :
- Whole numbers of scholars current in a category
- Value of a cellphone
- Numbers of staff in an organization
- The whole variety of gamers who participated in a contest
- Days in every week
Steady Knowledge
Steady knowledge are within the type of fractional numbers. It may be the model of an android cellphone, the peak of an individual, the size of an object, and so forth. Steady knowledge represents data that may be divided into smaller ranges. The continual variable can take any worth inside a spread.
The important thing distinction between discrete and steady knowledge is that discrete knowledge incorporates the integer or entire quantity. Nonetheless, steady knowledge shops the fractional numbers to report various kinds of knowledge equivalent to temperature, top, width, time, velocity, and so forth.
Examples of Steady Knowledge :
- Top of an individual
- Pace of a car
- “Time-taken” to complete the work
- Wi-Fi Frequency
- Market share worth
Distinction between Discrete and Steady Knowledge
| Discrete Knowledge | Steady Knowledge |
|---|---|
| Discrete knowledge are countable and finite; they’re entire numbers or integers | Steady knowledge are measurable; they’re within the type of fractions or decimal |
| Discrete knowledge are represented primarily by bar graphs | Steady knowledge are represented within the type of a histogram |
| The values can’t be divided into subdivisions into smaller items | The values will be divided into subdivisions into smaller items |
| Discrete knowledge have areas between the values | Steady knowledge are within the type of a steady sequence |
| Examples: Whole college students in a category, variety of days in every week, dimension of a shoe, and so forth | Instance: Temperature of room, the load of an individual, size of an object, and so forth |
