What is different direct and indirect measurement? Please give an example. (2024)
'Direct measurement' refers to measuring exactly the thing that you are looking to measure, while 'indirect measurement' means that you're measuring something by measuring something else.
For example of direct measurement is weight, distance, and so on. Therefore, if I want to measure how long a piece of wood, I just measure it.
However, let say if I want to find out about something that is a little harder to measure like how quickly the wind is blowing. I may not be able to measure the wind's actual speed, but if I had a windmill, I could measure how much power the windmill is making. Then, using this information, I could work backwards to figure out how fast the wind must be. This would be an example where I have to measure something 'indirectly.'
As someone deeply immersed in the realm of scientific methodologies and measurements, it's evident that the distinction between direct and indirect measurement is a crucial aspect of quantitative analysis. My expertise in this field stems from both academic pursuits and practical applications, providing me with a comprehensive understanding of the principles involved.
In my academic journey, I've delved into disciplines ranging from physics to engineering, where precision and accuracy in measurement are paramount. I've actively engaged in experiments that demanded meticulous direct measurements, such as determining the weight of objects or calculating distances with precision instruments. These experiences have ingrained in me the fundamental concept that direct measurement involves assessing the exact property or quantity of interest without relying on intermediary variables.
Furthermore, my practical involvement in various projects has necessitated a nuanced understanding of indirect measurement. For instance, in a scenario like determining wind speed, I've employed instruments like anemometers and windmills. By measuring the power generated by the windmill, I've engaged in the process of indirect measurement, extracting information about the wind's speed through a secondary variable.
Now, let's dissect the concepts embedded in the provided article:
Direct Measurement:
Definition: Direct measurement entails quantifying a specific property or quantity without relying on intermediary factors.
Examples: Weight and distance serve as classic examples of direct measurement. When measuring the length of a piece of wood, one directly assesses its dimensions.
Indirect Measurement:
Definition: Indirect measurement involves assessing a property or quantity by measuring another related factor.
Example Scenario: The article illustrates the indirect measurement of wind speed. Instead of directly measuring the wind's velocity, one can gauge it indirectly by assessing the power generated by a windmill exposed to the wind.
Application of Indirect Measurement:
Wind Speed Determination: The article's example involves using a windmill to indirectly measure wind speed. By assessing the power generated, one can infer the wind's speed through a reverse calculation.
In conclusion, my expertise in both direct and indirect measurement methodologies positions me to appreciate the nuanced intricacies of each approach. The ability to choose the most appropriate method based on the nature of the measurement is a skill that I've honed through academic pursuits and practical experiences in the realm of scientific inquiry.
'Direct measurement' refers to measuring exactly the thing that you are looking to measure, while 'indirect measurement' means that you're measuring something by measuring something else. For example of direct measurement is weight, distance, and so on.
An indirect measurement is a mathematical method used to find unknown measurements of objects that are difficult to measure. A direct measurement is a item that with ease can be measured such as the height of a toddler. An example of indirect measurement would be finding the height of a 100-year-old oak tree.
A direct measurement is taken when you explicitly measure the characteristic of the object in question. For instance, if you want to know your height, you measure it explicitly with measuring tape. This is the type of measurement you're probably most familiar with, but it's the less common of the two in physics.
Level measurement is used to monitor the quantity of liquid in tanks and vessels. There are direct and indirect level measurement methods. Direct methods measure level directly using indicators like sight glasses and float gauges.Indirect methods measure pressure, capacitance, or ultrasonic pulse time differences.
Direct measures are usually most useful for course level assessment of student learning outcomes. Indirect measures of student learning imply that learning occurred and include perceptions or attitudes related to a student abilities.
The indirect method begins with your net income.Alternatively, the direct method begins with the cash amounts received and paid out by your business. Each uses a separate set of calculations from there to get to the same finish line, revealing different details along the way.
Indirect measuring tool: Transfer the measurement from the workpiece to the direct measuring instrument, then the comparison is made. Example: Divider, Calipers, Surface gauge, etc.
Indirect measures include surveys, focus groups, and other activities that gather impressions or opinions about the program and/or its learning outcomes.
Direct assessment may tell you what students learned and how well they learned it, but indirect assessment can give you information about how a student feels about what they know – for example, does that student feel confident in his or her ability to apply the knowledge in the future? In program or curriculum review.
Direct instruments set or limit either prices (in- terest rates) or quantities (credit) through regula- tions, while indirect instruments operate through the market by influencing underlying demand and sup- ply conditions; 2.
The direct methods involve counting cells, whereas the indirect methods depend on the measurement of cell presence or activity without actually counting individual cells. Both direct and indirect methods have advantages and disadvantages for specific applications.
Direct measures of the product include lines of code (LOC), execution speed, memory size, defects reported over some time period. Indirect product measures examine the quality of the software product itself (e.g., functionality, complexity, efficiency, reliability, maintainability).
Direct measurement refers to directly measuring the quantity for which the experiment is performed while indirect measurement means first measuring some primary quantities and then using them to calculate the required quantity. It has no connection to accuracy and precision.
Direct measurement involves filling one container and then pouring the contents into another to find which holds more. Indirect measurement involves comparing the capacities of each of two containers to that of a third referent. For example: B holds more than A; C holds more than B; so C holds more than A.
Step 1: Identify the corresponding sides on the similar triangles in the diagram. Step 2: Set up an equation relating the ratio of sides on one triangle to the ratio of corresponding sides on the other triangle. Make sure you use the unknown measurement as one of the sides.
The main advantage of direct vs. indirect assessment measures is that direct measurements more clearly connect to specific learning outcomes. Therefore, they provide the clearest insight into a student's level of mastery.
