Title: Notebook computers should replace the traditional textbooks for students General Purpose: To persuade Specific Purpose: To persuade my audience to use notebook computers instead of textbooks for studying purpose I. INTRODUCTION (Attention) A. Attention Material/Credibility Material: 1. As a student what do you guys feel to carry a heavy bag filled with textbooks inside? Don’t you guys feel that was too much burden to move around every day to class with a heavy bag which also caused your

Level of Measurement. The measurements used would be nominal and ratio. The Spence Children’s Anxiety Scale (1994; See Appendix B for Spence Children’s Anxiety Scale) is similar to a five-point Likert scale, with the exception of being a four-point scale. The scales are ordinal because although they cannot be quantitatively measured, the qualitative questions can then be put into quantitative categories (Noia & Tripodi, 2008). Some of the scales are ratio because it has a true zero (Noia & Tripodi

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

The overall concept for chapter six concerns estimates of reliability for tests. This includes a review of measurement scales (nominal, ordinal, interval, and ratio), steps for the selection and creation of tests, and some of the more commonly used forms of reliability estimates (Cascio & Aguinis, 2011). Within the steps for selecting and creating tests, conducting an item analysis using item response theory (IRT) is also discussed. In addition, interpretation of reliability is included in the chapter

Measurement is defined as a process in which a numerical index is assigned to the characteristics or the attributes.it is also known as the process of quantification of the performance. There are many tools that are used for the purpose of measurement. These tools include tests, homework, checklist, projects and observations. For example in class a test is given to the students to check their skill or proficiency level and after that those tests are marked with numbers. So in this way we are translating

the community is 50, with a standard deviation of 10.” Murphy et al. (2002) further stated, “Each of the scales, excluding the validity scales (INC and CNV) and role orientation (ROR), are scored in a direction whereby higher scores reflect higher levels of relationship

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

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

1. Identify the key performance objectives Key performance objectives should be set realistically, can be used historic results as the starting point. Moreover, all relevant people who have responsibility should be identified with providing qualitative feedback on goal setting.Lastly, after setting the method how to achieve those objectives deadline need to be set (Sam Ashe-Edmunds, 2017). According to Coffeeville’s goals, which aim to grow the business by expanding the delivery routes to regional

Cooper and 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

Activity 3 (Individual and Group) US12444 SO1 AC1-7; EEK2, 3 Estimate, measure and calculate physical quantities to solve problems in practical situations: 1. John decides to double-check his estimated measurement before he buys the material and uses his tape measure to accurately measure the width of the window. He determines that the window is 2,2 m wide. a. How many metres of material does he need to buy? b. How much will the material cost? 2. Mr. Tshabalala has just finished building

In the experiment “Losing Your Marbles” we learned about momentum and conservation. We learned by dropping a marble down a ramp and timing how long it took it to get to a certain distance. Momentum means the mass, in grams, multiplied by the velocity, in cm/s. Or P= m x v. Conservation means something "stays the same." In this case it means that the momentum after a collision between marbles is the same as the momentum before the collision. In part one of this experiment we dropped a regular sized

Objective: The goal of this experiment is to determine the relationship between position (x) and time (t). The method that we took to construct this experiment was timing the amount of seconds the buggy took to get from one end point to the other. We are measuring how the time in which the buggy moves affects the position in which the bug is at. Materials: • Timer • 1 buggy • 2 meter sticks • Tape • Tape

\section{Facility Static and Dynamic Control}\label{Calibr} The facility calibration is the transfer function between the oscillating gauge pressure $P_C(t)$ in the chamber (described in ~\autoref{Sub31}) and the liquid flow rate $q(t)$ in the distributing channel, i.e. the test section. Due to practical difficulties in measuring $q(t)$ within the thin channel, and being the flow laminar, this transfer function was derived analytically and validated numerically as reported in ~\autoref{Sub32} and

amount of soil, amount of water, environment (same air quality, temperature, etc.), grass seed, number of grass seeds per cup, number of trials per level of I.V. and cups. The control in this experiment was 0 seconds on 100W. For this experiment, a relatively new and fully functional microwave was used. A total of five repeated trials for each level of I.V. were performed for this experiment. First, the necessary materials were gathered. These include 250 grass seeds, 25 paper cups, 3675 mL of soil

 When I did the conservation tasks with volume, number and length, I used two measuring glasses and one taller and narrower, two rows of 5 little bears, and two red pens. The first child was a girl of age 9. After we agreed that the water was equal in both glasses (one cup and one cup), I poured one in the taller and asked her the question: which one contains more water? The girl answer the taller one, because the water is higher than the other. For the other two tasks she answered that they were

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

Key Performance Indicator In the case of Key Performance Indicator (KPI), Bergfeld declares that it represents the progress of a certain task evaluated in terms of effectiveness and efficiency. The indicators can be seen as further analysis of the KSF, the KPI provide valuable data in how efficient a sequence task is done, describes what is needed for executing a task, the description of efficiency is quantifiable and can be scalar or percentage. KPIs become even more important when the Startup reaches

Anderson and Wood (1925) determined a magnification value equal to 2800 but they neglected the deformation of the tungsten wire under different equilibrium situations. Conversely, the deformation of the wire could be sufficient to reduce the magnification factor of 30%, increasing the moment of inertia. For this reason Uhrhammer and Collins (1990) and Uhrhammer et al. (1996) recomputed the instrument static magnification (GS) that was estimated equal to 2080 ± 60. Using 2800 instead of 2080 in the
