Analysis of concepts or ideas to give meaning to some national or world issues brainly

1. Why do you need an operational definition when you already have a perfectly good conceptual definition?

In your conceptual definitions you explain what your constructs are by showing how they relate to other constructs. This explanation and all of the constructs it refers to are abstract — their existence is only as real and concrete as the thoughts you have while you watch a seagull soar past on a stiff breeze. To work with your constructs, you must establish a connection between them and the concrete reality in which you live. This process is called operationalization. Your operational definitions describe the variables you will use as indicators and the procedures you will use to observe or measure them. You need an operational definition because you can't measure anything without one, no matter how good your conceptual definition might be.

2. Why can't you skip the conceptual definition and use only an operational definition to define your concept? i.e. why is it also necessary to have a conceptual definition?

A conceptual definition tells you what the concept means, while operational definitions only tell you how to measure it. If you have only an operational definition, you may know how to measure it, but you won't know what you are measuring. This means that your measurements won't be worth much, considering that you don't know what the concept is, so you don't know what you measured. A concept defined only operationally may make a nice little ceremony as you carry out the steps described by the operational definition, but it doesn't mean anything and it is not related to other concepts.

3. What is the difference between conceptual and operational definitions?

A conceptual definition tells you what the concept means, while an operational definition only tells you how to measure it. A conceptual definition tells what your constructs are by elplaining how they are related to other constructs. This explanation and all of the constructs it refers to are abstract. On the other hand, your operational definitions describe the variables you will use as indicators for youor constructs and the procedures you will use to observe or measure the variables.

4. A professor is studying learning and academic performance and uses GPA as a measure of how much her students have learned. Discuss why (or why not) this is an adequate operational definition of learning.

In order to evaluate this operational definition, it would be useful to know what it means to "learn" something. Is it necessary to memorize the material? If it you have memorized the material but you don't understand it, have you "learned" it? Do you have to be able to reproduce the information, or is it enough that you are familiar with it? At the same time, it will be useful to know what GPA measures and to what extent it measures how much was learned. Some people get high grades because they take courses that cover material they are already familiar with, so for them, GPA measures how familiar were they with the material before the course began, rather than how much they learned in the course. For other people, low grades may indicate that they did not like the instructors of their courses, that they had to work a lot of overtime for the last several months, or their allergies were making it difficult to sleep at night and they had trouble concentrating. These other factors are all things that could be having a larger effect on grades than how much the students learned. This illustrates the need to have a good conceptual definition so you know what the concept means. A knowledge of the essential qualities of your concept will help you develop an operational definition -- a measurement strategy -- that will provide a valid assessment of the concept.

5. What role should essential qualities play in operational definitions?

Since the specification of essential qualities as part of a conceptual definition tells exactly what the concept means, it gives some very good clues about how the concept could be measured in a most straightforward way. Essential qualities should play a central role in operational definitions in that the measurement procedures should be explicitly designed to look for the presence or absence of the essential qualities.

6. What is the difference between a numeral and a number?

Numerals are symbols composed of one or more of the characters from 0 to 9, and used as labels to indicate which category something belongs to. They are only symbols, like letters, and they have no mathematical meaning. You cannot do valid arithmetic with numerals. Wayne Gretzky's "99" is an famous example.

Numbers are symbol composed of one or more of the characters from 0 to 9, possibly including a decimal point or a leading minus sign. While a numeral indicates which category something belongs to, a number can indicate how many objects there are, how much of something there is, where something is located along a continuous scale, or how many steps it is along a discrete scale. Unlike numerals, numbers have mathematical meaning and can be used in arithmetical comparisons ("greater than" or "less than") and operations (addition, subtraction, multiplication, and division).

7. What is the difference between a number and an ordinal?

Ordinals look a bit like numbers, but they only tell what order things are. Examples are 1st, 2nd, 3rd. No mathematical operations can be performed on ordinals.

Numbers are symbol composed of one or more of the characters from 0 to 9, possibly including a decimal point or a leading minus sign. Numbers have mathematical meaning, whereas ordinals only specify ordering relationships.

8. In what way is ratio scaling "stronger" than interval or ordinal scaling?

As you move from nominal to ordinal to interval to ratio, the numbers in the data contain more amounts and more kinds of information about whatever it is the numbers represent.

With ordinal scaling you can tell if one case comes before or after another case, but not how far before or after. With interval scaling you can tell if one case is larger or smaller than another case, and how much larger or smaller.

What is analysis of concepts or ideas to give meaning to some national or world issues?

Conceptual Review: analysis of concepts or ideas to give meaning to some national or world issues 2. Critical Review: Focuses on theories or hypothesis and examines the meanings and results of their application to situations 3.

Which of the following is the true definition of what research is?

Research is defined as the creation of new knowledge and/or the use of existing knowledge in a new and creative way so as to generate new concepts, methodologies and understandings.

What is research all about brainly?

Answer: Research is a process of systematic inquiry that entails collection of data; documentation of critical information; and analysis and interpretation of that data/information, in accordance with suitable methodologies set by specific professional fields and academic disciplines.
