type of scale? • Nominal scale , categorize the variable only in the way to measure differences • Ordinal scale , categorized and rank-order variables in some meaningful way • Interval Scale , categorized and rank-order variables in some meaningful way and measure the distance between any two points on the scale • Ration scale , categorized and rank-order variables and measure the distance between points and also taps the proportions in differences 2. How is the interval scale more sophisticated

another in terms called levels of measurement. Nominal measures classify observations into mutually exclusive and exhaustive categories. They represent nominal variables such as sex, ethnicity, religion, and political party preferences. For the purpose of data collection a number might be assigned to each category. Ordinal measures are at a higher value then nominal numbers because categories have a fixed order. Interval measures share the characteristics of ordinal scales, mutually exclusive and exhaustive

Results from fluctuations in the readings of a measurement apparatus, experimenter's interpretation of the instrumental reading or randomly changing conditions (weather, humidity, etc.). - Can be reduced by averaging multiple measurements. - Unbiased - Affects precision Uncertainties in Measuring Devices General rule of thumb used to determine the uncertainty in a single measurement when using a scale or digital measuring device. 1. Uncertainty in a Scale Measuring Device is equal to the smallest increment

Measuring Aids stigmas in people living with HIV/AIDS: the Internalized Aids-Related Stigma Scale. 1. Write a brief description and summary of your article. The objective is to measure the psychometric properties of instruments to measure Internalized Aids-Related Stigmas. This article talks about the psychometric measurement of people living with Internalized Aids Related Stigmas (IARS) and the effect that IARS has on communities and individuals. It reviews the notion that stigma is the

oscilloscope. In this lab, electrical signals were measured using the oscilloscope in both time domain and frequency domain. Two electrical signals were displayed- a 1 kHz, 2.78VPP as well as a 2 kHz, 278mVPP. In this lab, methods of improving measurement accuracy, dealing with floor noise and averaging were all explored. Overall this lab was a useful tool in understanding the lab equipment. RESULTS AND DISCUSSION: PART 1 - QUESTION 1 i) A 1 kHz, 2.78 VPP sinusoid wave is displayed with trigger

pattern as to why there is a growing unhappiness with current employees and use it to understand why the past employees did leave the company. The research questions are mostly in the ordinal level of measurement and are quantitative in nature because they are given numerical values on a likert scale. Calculating the average of these questions will give us meaningful data in which to

pets were given an informed consent that was approved by the Institutional Review Board of Rutgers (Krause-Parello, 2008). The study instruments included; PGWB schedule, a general health subscale, The Revised UCLA loneliness scale and the Pet attachment scale. The scales used various psychological tests measuring depression, loneliness and psychosomatic symptoms. The data were analyzed using Pearson product-moment (questions one through three) and regression analysis (question four) (Krause-Parello

trucks and the ineffectual time of the scalers. The number of trucks arriving during any given hour needs to be determined and the Poisson Probability Distribution has been applied. Having two open scale stations that cover 57.60% of the data would be the best option. Still, having four open scale stations there is a 99.93% chance that zero trucks would have to wait, but there would be a 3.74% chance that a truck will even need the extra station and you would likely be paying scalers for complete

Measurement in Accounting: What is the Scale? In the last few years the field of accounting has been the subject of a critical review,the intensity of which is increasing as time goes by. Somehow, both within and without the accounting profession, there is a feeling of dissatisfaction with the information generated by the accounting process. Such dissatisfaction is leading to questions about the fundamental bases of Accounting. The practitioner claims to identify,collect,measure,record,analyse
