All of last week we worked on building mousetrap cars. I briefly described them in my last blog post but on this post I will make a more detailed blog about what I struggled with and what went well for me and the whole process I went through while making this car. The first mousetrap car that I made was a total disaster. I tried to do something different from what everyone else was going, to see if I could create something that would be more successful in some aspects also because the pictures

In this lab, we collected a multitude of samples of water from our area. After collecting them, each sample was put to numerous tests to—ultimately—see the quality of the water surrounding us every day. However, even though each sample and test was conducted as correctly as possible, some errors may have occurred that could have altered or skew our results. Also, environmental areas and external forces may have some influence on the data and results we collected from this lab. Even more so, since

The main outcomes that were used to determine change were the TUG and OGS. The TUG is commonly used in the adult population to assess ambulatory mobility or balance, however, has not been commonly used in pediatric populations.12 This measure can be used to assess change in gait over time when interventions are directed toward affecting gait.12 Williams et al. determined that the TUG has a high level of reliability (intraclass correlation coefficients of 0.89 within session and 0.83 for test-retest

The GAD-7, designed by Spitzer et al., is a brief scale that measure anxiety. It is consisted of 7-item self-report questionnaires to identify and rate symptoms. Correspondingly from zero to three, the response options were “not at all”, “several days”, “more than half the days”, and “nearly every day”. To test the reliability of the measure the researchers used test-retest. The test-retest reliability came out to be 0.83, which is reliable, because it was greater than 0.70. The construct validity

Validity A Management Information System must be valid and accurate so the organization can take an accurate decision. An example of valid and accurate information is gathering the information directly from the person that produces the information, instead of a third-party. If the Wonder Land Resort wants to analyse their revenue for the year, they’ll gather the information from their financial team instead of a third-party. Since the financial team is within the company and is a trusted source

result. These situations affect the level of motivation a student harness when studying. The feeling of unfairness affects how he/she will prepare for the next exam. In the workplace setting, motivation is likewise an important factor to increase productivity. For example, an employee who worked overtime to get the job well done vis-a-vis an employee who slacked off and produced a mediocre output both received the same salary and the same praises from their boss. The hardworking employee might feel

These levels are often referred to as levels of measurement. This first level is known as a nominal level. Within this level, data is sorted into categories without an order. The second level is the ordinal level. This is where the level of measurement decides if any one category is to be ranked higher than another. The third level is known as the interval level. Within this level, “the ranking characteristics of the ordinal level of measurement plus the characteristic that the distance between

problem occurred, Ron Bent, the plant manager, had adopted the Scanlon Plan. The Scanlon Plan was an incentive plan used to motivate employees and to drive changes in their behavior and attitudes. The plan consisted of monthly bonuses for employee productivity, communication meetings, a committee to encourage and evaluate employee’s suggestions, and overall improved working conditions. Employees were satisfied with their jobs and motivated to be productive. Over time, changes needed to be made to adjust

based on four major forms of validity: internal, external, construct, and statistical conclusion. The second framework comes from the field of survey research and different sources of bias and variance into errors of representation and errors of measurement. The researchers concluded that a series of new studies be conducted to provide a direct comparison of the findings from classic experimental design with the findings from an otherwise comparable quasi-experimental design. This series of new methodological
