Level of measurement

recognizes that "what gets measured, gets done" (Peters, n.d.). Given the company 's strategic plan for improving performance, a senior manager must define and establish key performance indicators to measure effectiveness and progress. Once the measurement criterion is formulated, a business rhythm for acquiring performance data must be instituted. The monitoring and controlling mechanisms to track performance require collaboration and participation from Regional Managers, Sales Managers, and…

controlled conditions indoors and the sit and reach test is a field based tests though it can be performed indoors too. When testing the validity of the sit and reach test it is hard to be accurate with the results because other factors such as the measurement or the individual’s arm length can play a vital role when it comes to the validity. If the performer isn’t able to get the same results when performing the same test then the validity of the results is not accurate, where as if we were…

twice and if the results are consistent both times then the test is reliable. There are types of reliability; stability or test- retest, alternate form and internal consistency as Rose (2013) asserts. On the other hand, validity refers to the accuracy level of an assessment. In other words it is a determination of whether an assessment accomplishes the set purpose of measuring what it was supposed to measure as Rubin & Babbie (2010) acknowledge. In research these two aspects are very crucial for…

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…

There was a pattern revealed in the results, within the three trials of all pH levels they were all consistent numbers. Also, when the pH is acidic there will be very little oxygen produced, when the pH is neutral it will have the highest enzyme activity and when its basic it will start to produce less oxygen again. Each pH level had different concentrations, pH 4.8 which was the most acidic produced 2, 1 and 2mls of foam. pH 5.3 which is slightly acidic produced 2, 4 & 2mls of foam. pH 7.4…

While monitoring CSR activity, roughly we need to monitor it by three methods, as follows : 1. Internal Compliance Monitoring & Measurement 2. External Monitoring & Measurements ● Internal Compliance Monitoring Monitoring and Evaluation are essential components for ensuring that CSR Initiatives are effective and are giving desired results. Monitoring and Evaluation can provide us with detailed information regarding the performance of policies, programmes and projects carried out in the…

Measurements and Collection. In order to show the effect of the structured intervention on the outcomes of the mentees, different types of data will be collected and analyzed to detect trends over time between mentoring groups (E-SBM, Traditional BBBS, and Control). Along with demographic data collected upon program entry, data will be collected on multiple measurements corresponding to each hypothesis. - The first intermediate question states: What is the difference in behavior between each…

the LifeShirt, an “electrophysiological measurement device” (see below). Once a 30-minute period had passed, an initial saliva sampling was taken from the volunteers. Then, each volunteer was taken into the TSST room,…

Test-retest reliability can be a useful assessment for a survey instrument. “Test-retest reliability provides information on how consistent a measure is when it is administered twice in a relatively short time frame. The appropriate length of that time frame will vary with both the instrument and the target population” (Krysik & Finn, 2013, p.266). In addition, the interval needs to be extended so that the subject cannot recall the answers and short enough to make sure that no changes occur in…

the closeness of two or more measurements together. In the above table, it is evident that the average weight difference for potatoes that were placed in sucrose (0.00g) and glucose (0.01g) are reliable. This can be shown through the increase of 0.01g as seen above. The potato which was placed into the ethanol solution can also be classified as precise, as the average weight difference is identical to that of the weight difference caused the glucose solution. Low levels of precision can be…
