VTAC Scaling

VTAC Scaling - VTAC adjusts the study scores for each study to take account of the overall ability level of the students and hence the strength of competition in the study.

The overall ability level of the students in each study is measured by how well the students performed in all their studies.

In each study, the study scores are adjusted so that the overall level of scores in that study matches the scores obtained by the same group of students in all of their studies.

For example, in economics in 2009 the average VCE Study Score was 30, but the students averaged 32 for all their studies. This shows that students who did economics in 2009 were of above average ability in their other studies.

VTAC Scaling

The scaling process adjusted the study scores upwards so that the average ENTER Subject Score for economics was set at 32. (Note: the acronym ENTER was changed to ATAR this year.)

The 2009 dance students averaged 28 in all their studies, therefore the scaling process adjusted the study scores downwards so that the average ENTER Subject Score for dance was 28.

In some studies the scaling process produces ATAR Subject Scores that are greater than 50. However, the minimum ATAR Subject Score cannot go below zero. VCE studies are always scaled in the year in which they were undertaken (this may not necessarily be in the year in which you receive your ATAR). This scaling process is carried out each year for each VCE study and VCE VET program for which there is a study score.

There are no predetermined outcomes, the adjustments are based on the performance of students each year.

Nevertheless, the process is stable and there is little difference from year to year in terms of the scaled ATAR subject scores.

Urban Meyer Stepping Down

Urban Meyer Stepping Down - Well, it appears as if it’s deja vu all over again.

Less than 12 months after retiring and then un-retiring, Urban Meyer is apparently stepping down as Florida’s head coach. There’s no word on if he will be stepping back up tomorrow.

Urban Meyer Stepping Down

According to Todd Wright of Sporting News radio, and AOL Fanhouse‘s Brett McMurphy Meyer will announce at a 5 p.m. ET press conference Wednesday that he is resigning/retiring as the Gators’ head coach. There are no further details available at this time, other than GatorUpdates reporting over the weekend that Meyer checked into a hospital the week of the UGA game and has been undergoing tests since.

Obviously, we’ll have more on this story throughout the day and well into the night…

Matt Cassel Undergoes Appendectomy

Matt Cassel Undergoes Appendectomy - The mystery of Matt Cassel missing practice Wednesday coupled with the Kansas City Chiefs promoting quarterback Tyler Palko has been solved.

The team has announced that Cassel underwent an appendectomy on Wednesday morning. The Chiefs say they expect Cassel to return to work this week. Returning to work and being ready to perform well in the team’s biggest game of the season on Sunday against San Diego are two different things. ESPN’s Adam Schefter is reporting the Chiefs are viewing Cassel as being questionable to play in the game.

Clearly, this is terrible timing. The Chiefs are 8-4 and would take a major step toward the playoffs with a win over the Chargers. Cassel has played very well for the past two months. If he can’t play, the brittle Brodie Croyle would face the Chiefs in his first action of the season. Croyle last played in Week 13 of the 2009 season.

100-calorie Packs Diet

100-calorie Packs Diet - Did you know recent studies show chronic dieters tend to consume more calories when foods and packages are smaller? Consumer behavior was observed in the study regarding "mini-packs," 100-calorie food packages that are marketed to help people control calorie intake.

The study revealed that one group that over-consumes the mini-packs is chronic dieters - individuals making a conscious effort in trying to manage their weight and food intake.

This shows that the distorted perception of small packages may actually undermine dieters' attempts to limit calories.

Consider this: Consumers perceive the mini-packs to be a generous portion of food - numerous small food morsels in each pack and multiple mini-packs in each box - while on the other hand, consumers perceive the mini-packs to be diet food. For chronic dieters, this perceptual dilemma causes a tendency to overeat, due to their emotion-laden relationship with food.

In a series of focus group studi…
