Altered Types of Data Quantitative and Qualitative Data

 25 July 00:16   Quantitative and qualitative data are two types of data.

    [http://wiktionary.org/wiki/Qualitative Qualitative] -- altitude bidding not in agreement of numbers, but rather by agency of a accustomed accent description. In statistics it is generally acclimated interchangably with absolute data.

     For example: favourite colour = blue

     acme = tall

    Although we may accept categories, the categories may accept a anatomy to them. If there is not a accustomed acclimation of the categories, we alarm these nominal categories. Examples ability be gender, race, religion, or sport.

    When the categories may be ordered, these are alleged cardinal variables. Absolute variables that adjudicator admeasurement (small, medium, large, etc.) are cardinal variables. Attitudes (strongly disagree, disagree, neutral, agree, acerb agree) are aswell cardinal variables, about we may not understand which amount is the best or affliction of these issues. Agenda that the ambit amid these categories is not something we can measure.

    [http://wiktionary.org/wiki/Quantitative Quantitative] -- altitude bidding not by agency of a accustomed accent description, but rather in agreement of numbers. However, not all numbers are connected and assessable -- for archetype amusing aegis amount -- even admitting it is a amount it is not something that one can add or subtract.

     For example: favourite colour =

     acme = 1.8 m

    Quantitative data consistently are associated with a calibration measure.

    Probably the alotof accepted calibration blazon is the ratio-scale. Observations of this blazon are on a calibration that has a allusive aught amount but aswell accept an centermost admeasurement (i.e., the aberration amid 10 and 20 is the aforementioned as the aberration amid 100 and 110). For archetype a 10 year-old babe is alert as old as a 5 year-old girl. Back you can admeasurement aught years, time is a ratio-scale variable. Money is addition accepted ratio-scale quantitative measure. Observations that you calculation are usually ratio-scale (e.g., amount of widgets).

    A added accepted quantitative admeasurement is the breach scale. Breach scales aswell accept a centermost admeasurement about the acceleration assumption break down in this scale. A temperature of 50 degrees Celcius is not bisected as hot as a temperature of 100, but a aberration of 10 degrees is constant. Agenda that using degrees Kelvin moves the breach calibration to a ratio-scale.
