Concepts What are they? As much as we might want to embrace the . The four scales of measurement are nominal, ordinal, interval, and ratio. Therefore, research means the measurement of the variables and the importance of the variable is hidden in this concept. Measurements play an important role in daily life because they are useful to do basic tasks, such as take a child's temperature with a thermometer, make time estimations, measure out medicine and find weights, areas and volumes of different materials or substances. While we look at these various categories as stoic forms of mathematical measurements a closer examination of things we do in everyday life reveals their clear importance. Proper selection of units and accurate measurement of items are very important in our daily life.

Strohmetz, Ph.D. Last modified by: David B. Strohmetz, Ph.D. Research May be Obtrusive or Non-Obtrusive Article Summary: On a baseline level, measurements fall into the categories of weight, area, volume, length and even temperature. This element also emphasizes under-standing what these attributes really mean, that is, fully understanding the underlying concepts … measurement highlights the importance of finding the most appropriate attributes to study in a research area. Basically, the variables should be determined in accordance with their purpose and components. Without measurement and evaluation, it is impossible to know whether students are making any progress. Education is effective when students improve over time. Measurement of weight, volume, length and time has now become a part of our daily life. The types or levels of political actor to which the hypothesis is thought to apply e.g., actor (country, individual, agency); event (election, conflict) Should be In other words, the variables should be selected through operational words and research literature. appropriately termed scales of measurement. Ch. Basic Research (Pure) adds to the existing body of knowledge; doesn't necessarily provide results of immediate, practical use. Those methods that researchers use in collecting his desired data are known as research or measurement instrument. 10 Everyday Reasons Why Measurement is Important in your Life?

First, you have to understand the fundamental ideas involved in measuring. The Building Blocks of Social Scientific Research: Unit of analysis Concepts are key! Measurement is the process of observing and recording the observations that are collected as part of a research effort. Quantitative Research Non-Experimental ---SURVEY Experimental CAUSE AND EFFECT PRE-TEST/POST-TEST LABORATORY Quantitative Research Survey- quantitative or numeric description of some part of a population A “sample” via questionnaire (if people are involved) Results enables researcher to generalize the findings from a sample of responses. There are two major issues that will be considered here.
