What is Data?
Datum is the singular form of "data". And refer to a standard position or level that measurements are taken from.
Data is a plural of datum, a single piece of information; data is used in singular and plural form of word. Data is often used for binary machine readable information
Data can be found in a variety of forms, as numbers or text on papers and as bits and bytes in electronic devices or facts stored in person’s mind.
Data can be divided into two types:
Qualitative Data : The term qualitative is used to describe certain types of descriptive information . Data can be observed but not measured. e.g. Colors, textures, smells, tastes, appearance, beauty, etc
Quantitative Data: The term quantitaive is used in which items are described in terms of quantity and in which a range of numerical values are used without implying that a particular numerical value refers to a particular distinct category. Data which can be measured. e.g. Length, height, area, volume, weight, speed, time, temperature, humidity, sound levels, cost, members, ages, etc.
Quantitative data can also divided into two types
Discrete Data: A type of data is discrete if there are only a finite number of values possible or if there is a space on the number line between each 2 possible values. It can only take whole numbers, which can only be counted.
Continuous Data: This is a type of data that is usually associated with some sort of physical measurement. Can take values in range, and is measured. One general way to tell if data is continuous is to ask yourself if it is possible for the data to take on values that are fractions or decimals. If your answer is yes, this is usually continuous data
