Observations and Measurements

The questions posed should be reflective of your goals and should appeal to a large audience. Committees always want to know your potential and if you can convey your ideas effectively. Before starting, find out what most interest you, not you advisor nor anyone else. If no ideas come to mind, refer back to previous studies for ideas. Develop your questions, and don’t be obsessed about perfection; a lot of factors in field work are out your control, so try several experiments at once, and work…

test Socrates thesis of justice with the likes of observing, measuring, and experimentation. Socrates path of attempting to define justice and describe his perfect city was a battle of philosophical questions and answers, not concrete facts or observations in which allows one to come to a definite and repeated answer of veracity. One could identify this when Socrates attempts to disprove his colleagues position on justice, asking each one various questions which ultimately makes his victims…

400 mL of White Vinegar Tap Water 400 mL of Corn Syrup Graduated Cylinder---500 mL Raw Egg in Shell Ruler Masking Tape Permanent Marker Paper Towels Procedure 1)Look at the raw egg, and study the appearance of the eggshell. 2)Take measurements of its mass and circumference. Record your information in a data table. 3)Use a graduated cylinder to measure 400mL of vinegar. Pour the vinegar into your cup. 4)Place the raw egg into the cup with vinegar. It should be covered. 5) Leave…

A system called CWEED, which measures energy in Ontario and it can "provides solar global measurements as the total of direct and diffuse radiant energy received by a pyranometer." (Hoicka, Rowlands,2011). Therefore, an efficient system can determine whether citizens have easy access to reliable energy or not. However, in some developing countries…

Questionnaire-related Measurement Error Questionnaire- related measurement error could have occurred in a couple questions within our survey because of the way that the questions were worded and the possible answers that were listed. One of the questions where this occurred was in question 8 that asks, “Should the U.S. immigration laws be made stricter, looser, stay about the same, or are you uncertain?” This represents a questionnaire- related measurement error because this question does not…

Standardized Testing Is a Flawed Measurement Standardize testing fails at its one and only job. The ACT and SAT are standardized test, which are taking by high schooler’s as a requirement for college acceptance. Chiefly, the testing evaluates the primary subjects, including math, science, reading and writing. However, the testing material is fashioned by the financially-driven testing business, that is a multi-billion-dollar industry. No surprisingly, the testing industry charges…

J. Connolly et.al [28] also propose a wearable rehab technology for automatic measurement of patients with arthritis. They put forward the ideas surrounding the development of an accurate hand measuring tool to assist medical clinicians and rheumatologists in the accurate measurement of finger and thumb movement of the human hand. Angle measuring instruments, tape measure and grip strength dynamometer are used to assess the joint range and function of a patient to determine their hand function.…

meaning of, and relationship between, “reliability” and “validity” ? • Reliability is the extent to which a measuring tool gives consistent results. Reliable means to be consistently accurate, also describes as the absence of random error during measurement. There are three types of reliability: items of reliability, stability, and interobserver. • Validity is the extent to which a measuring tool measures what is supposed to measure. The process of validation includes verifying evidence…

Purpose The purpose of the lab is to design an experiment to verify the spring constant for an unknown spring, also known as k, how much a spring resists change (compression or expansion). We used a method changing a mass and measured the change in x.
