  • Chemistry: Measurements And Significant Figures

    275 Words  | 2 Pages

    Measurements and significant figures are important in Chemistry because it shows how accurate something is, and it shows which place value is the estimated one if/when used correctly. In this lab, the density for water that was found is 0.99g/mL and the percent error was 1%, and 1% is good. An error that could have occurred while finding the density for water was that the measurement were not exactly correct because not everything is going to be perfect. The density for Copper that was found was

  • Why Is Metric And SI System Better To Use In Measurement?

    1050 Words  | 5 Pages

    Physics Coursework 1.1(a) Discuss why metric and SI system is better to use in measurement. Explain and list at least 6 physical quantities scientists use in measurements. There are several reasons as to why using the Metric System and SI Units are better to use. Each measurement has only one unit of measure regardless of the size which makes it a lot simpler to understand. Another factor that makes the metric system a better system to use is that the units use the same conversion, for example, 10

    and let the spring come to rest. After that, I pulled the spring down 10cm and released. I recorded the point at which the spring’s rebound stopped. I repeated this step two more times. I recorded the information on a chart. I then averaged these measurements and recorded it on the chart. Next, I took a 100g weight and placed it on the end of the spring. I let the spring come to rest. After that, I pulled the spring down 10cm and released it. I recorded the point at which the spring’s rebound stopped

    instrument” (LoBiondo-Wood & Haber, 2014). An example of reliability in research would be weighing a person five times on the same scale and receiving consistent weighs each time. 2. Validity Validity is defined as “determination of whether a measurement instrument actually measures what it is purported to measure” (LoBiondo- Wood & Haber, 2014). An example of validity is weighing a person five times on the same scale and receiving the exact weigh each

    efficiency), but no concrete means of measuring. Finally, 7.b wants to aid the developing community, and yet, since it requires only the building and expanding of infrastructure and technology, there is no definite end-goal and thus no easy measurement

  • Correlation Between Height And Adulthood: A Case Study

    and physiology, it is a standard assumption to claim that there is a distinct correlation between an individual’s height and wingspan. Wingspan can be defined as the extent across a person’s arms from fingertip to fingertip, while height in the measurement from someone’s feet to the top of their head. The typical human body has a height that matches a person’s wingspan. For instance, if you are five foot tall, you are assumed to have a wingspan of five feet. The correlation between height and wingspan

  • Reliability And Validity Essay

    2306 Words  | 10 Pages

    For example, if I use the measurement twice (e.g. take a test twice) would my scores be the same? Reliability focuses on the consistency of the measurement. If a measurement is reliable you should get the same results if you repeat it. With any measurement the score you get is the observed score. This score is a combination of the true score and error score. Researchers would of course like to eliminate or at least minimize the error score. Four sources of measurement error include: (i) Subjects

    Brittney Ingraham BADM 520 Quiz #4 October 24th 2015 1) What are the main criteria for evaluating measure validity? There are 5 different types of validity that are used for evaluating measure. The first criterion is making sure the measure has face validity. Face validity of the measure means that it accurately describes the concept being studied. An easy way to think about this if you make a bakery, you want people to walk in and know it’s a bakery; you cannot sell cars at your bakery and expect

    following items, what did you find most challenging in making the measurement and how did that challenge affect the accuracy of the measurement? a) Length of the table b) Height of your partner c) Thickness of your finger A. We found that measuring the length of the table was difficult because it was longer than the two-meter stick. To measure the table we used the two-meter stick and a meter stick together. Overall I believe the measurement was slightly less accurate because we had to check three points

    colleagues (2007) discuss the need to carefully select and train observers since this is necessary for the collection of accurate and trustworthy data. Potential observers should be interviewed to determine their level of experience with observation, measurement, and data collection since if any part of the intervention is not implemented, measured, or recorded correctly, the intervention will be inaccurate and unreliable. Once an observer or observers have been selected, training on recording the dimension

    The targets in goal 13 vary on their ability to perform measurably. To begin, Target 13.1 can be measured by comparing how well a country deals with one natural disaster vs. another. However, other factors must be considered such as the intensity of the disaster, the resources available, etc. Target 13.2 is easily measurable, by comparing national policies and seeing whether climate change measures really have been implemented. Target 13.3 however, is arguably measurable as different strategies to

    Recommendations for additional operational performance metrics would include tracking cost of goods sold and the level of qualification for potential candidates. The cost of goods sold performance metric will help Wasabi understand the total cost involved in creating menu items that will be sold to guests (Austin, 2016). Cost of goods sold analysis will allow the restaurant to reduce costs to inventory, labor, etc. where necessary, thus allowing the establishment to lower prices to consumers. The
