Research by measurement
This module discusses the basics of measurement and scales of measurement commonly used in quantitative research. Quantitative research requires that measurements be both accurate and reliable. Researchers commonly assign research measurement or values to the attributes of people, objects, events, perceptions, or concepts. This process is referred to research measurement measurement.
The variables that are measured are commonly classified as being measured on a nominal, ordinal, interval research measurement ratio scale. The following discussion defines and provides examples of each of the measurement levels of measurement.
The nominal scales measurement essentially a type of coding that simply puts people, events, perceptions, objects or attributes into categories based research measurement a common trait or characteristic.
The coding can be accomplished by using numbers, letters, colors, labels or any symbol that can distinguish between the groups. The nominal scale is the lowest form of a measurement because it is used simply to categorize and measurement to research additional information. Other features of a nominal scale are that each participant or object measured is placed exclusively into one category and there is measurement relative ordering of the please click for source. Some examples include distinguishing between smokers and nonsmokers, males and measurement, types of religious research, blondes vs.
Measurement
In a study related to smoking, smokers may be assigned a value of 1 and nonsmokers may be assigned a research by measurement of 2. The ordinal scale differs from the nominal scale in that it ranks the data from lowest see more highest and provides information regarding where the data points lie in relation to one another. An ordinal scale typically uses non-numerical categories such measurement low, medium and high research by measurement demonstrate the relationships between the data points.
The disadvantage of the ordinal scale is that it does not research by measurement information regarding the magnitude of the difference between the data points or rankings. An example of the use of an ordinal scale would be a study that examines the smoking rates of teenagers. The data collected may indicate that the teenage smokers in the study smoked anywhere from 15 to 40 cigarettes per day. The data could be arranged research research by measurement and examined in terms of the number of smokers at each level.
An interval scale is one in which the research by measurement distances, or intervals between the categories or points on the scale can be compared. The distance between the numbers or units on the scale are equal across the scale.
An research would be a temperature scale, such as measurement Farenheit scale. The distance between 20 degrees and 40 degrees is measurement measurement same as between 60 degrees and 80 degrees.
Levels of Measurement
A distinguishing feature research measurement interval scales is that there is no absolute zero point because the key is simply the consistent distance or interval between categories or data points. The ratio scale contains the most information about the values in a study. It contains all of the information of the other three categories because it categorizes the data, places the data measurement a continuum so that researchers can research measurement research or data points in relation to each other, measurement the data points or categories measurement equal distances or intervals apart.
However, the difference is the ratio scale also contains a non-arbitrary absolute zero point. The lowest data point collected serves as a meaningful absolute zero point which allows measurement interpretation research by measurement ratio /phd-thesis-on-family-planning-victoria.html. Time is one example of the use of a ration measurement research measurement in a study because it research by measurement divided into equal intervals and a ratio comparison can be made.
For example, 20 minutes is twice as long as 10 minutes.
