Percentile

Preparation Firstly, to prepare for the first administration of the CAS, I read the examiner manual which explained that in order for the results to be interpretable and avoid reducing of reliability and validity, the assessment should be administered according to the procedures and recommended testing conditions (Das & Naglieri, 1997). There were several key points to be familiar with which are: the materials needed in each subtest (ie. Response book, red pencil, stopwatch), the starting points

this chapter was new to me. For example, I had no idea how to calculate percentile. Additionally, the terms quartile, decile, and stanines were new to me. Finally, I have heard of z scores and t scores. However, prior to reading this chapter, I was unaware of how they were used. Several of the terms defined in this chapter I was familiar with include raw scores, norm-reference scores, criterion-reference scores, and percentile ranks. I really like how Salkind presents the information in this chapter

scored based on age in years and months, and the score is then compared to same-age peers. The PPVT is considered a good indicator of overall verbal ability. Felipe’s score for the PPVT is as follows: Standard Score 116 Percentile Score 86% Stanine Score 7 Felipe had a percentile score of 86%, meaning he scored higher than 86% of peers his age. His score indicates a receptive (listening) vocabulary that is moderately higher than his peers.

Central phenomenon (McMillan, pp. 52-53) – the focus of qualitative research. Virtual school curriculum could be studied and the central phenomenon would be who writes the curriculum and what resources are included in the curriculum. Dependent variable (McMillan, p.39) - the item that responds to alterations of the independent variable. In my professional practice I would research the effectiveness of virtual schooling with regards to standardized testing. In my experience students who exclusively

2. What is a standard score? A standard score is a scores that enables us to refer to the performance of an individual pupil in relation to the whole population where the mean is 100 and the standard deviation is usually 15. It also allows schools to base their assessments per school year. This is due to standarised scores taking into account the age of the pupil. A pupil in year 9 that has a date of birth of September would generally be expected to get a higher raw score than a pupil born in

Purpose: Jane agreed to volunteer as a test subject for a graduate student in training for an achievement assessment. Background Information Jane Porter is a 21-year-old white female who lives with her father, Archimedes Quincy Porter, a scientist in England. According to her father, she was born healthy with no medical problems or difficulties and met developmental milestones within average/expected limits. Jane is in good health and reports that she has never had any serious medical problems nor

Further, domain level percentile rank will be calculated for each of the five domains by calculating the sum of the percentile ranks of the variables in that domain. Finally, an overall percentile rank for each tract will be calculated as the sum of the domain percentile rankings. In addition to total SVI, we will include a count of the number of individual variables with percentile ranks of 90 or higher for each of the five domains and for the tract/block group overall. The total flags variable

Z’s score fell in the 1st percentile in both auditory comprehension and expressive communication. What this means is that Z scored as well or better than 1% of the sample population of children her age, but 99% of other children her age achieved a higher score. e. Age-equivalent scores

1. If the percent of sedans that gives more than 44 mpg is 0%, z-score is 4.33. 2. 16.13% of sedans give between 33mpg and 35 mpg. The Z-score for 33 is.67, and the z-score for 35 is 1.33 3. 10.10% of mid-size sedans will give less than 27mpg or more than 38mgp. The z-score for 27 is -1.33, and the z-score for 38 is 2.33. 4. To develop a sedan that outperforms 90% of the current sedans in fuel economy the gasoline usage rate would be 34.84 with a z-score would be 1.28 5. To determine the normality
