There is a 25% improvement.
A variable that has been transformed by multiplication of all scores by a constant and/or by the addition of a constant to all scores. Often these constants are selected so that the transformed scores have a mean of zero and a variance (and standard deviation) of 1.0.
No, the scores are the results, the data. The variable would be the food.
An advantage of using a z-score is that it allows you to compare two scores in the same manner. ?æIt standardizes the scores so that they can be compared to one another.?æ
Controls are used to show that the test, equipment, procedure...are working properly. One would expect negative controls to give negative results and positive controls to give positive results. Controls used would depend on the experiment.
A negative correlation is when you compare 2 sets of data on a line graph (e.g. scores in a French test and scores in an English test), the higher one thing is, the lower the other is (e.g. someone might score 98% on the French test but only 12% on the English test (or visa versa)). A positive correlation is the other way around. A weak correlation is when there is a lot of deviation from the line of best fit (there will always be one with correlations as a line of best fit shows correlations after all) whereas with a strong correlation, there is little deviation.
You get a "+1" for being on the ice when your team scores and a "-1" when your on the ice when the opposing team scores
This question cannot be answered unless the bowling scores are provided.
seriously? alma.. :)
The sanctioned ABC 300 games or 800 series scores bowled can be found at the USBC International Bowling Museum and Hall of Fame in Arlington, TX.
Yes, although the z-scores associated with p-values of 0.01 and 0.05 have special significance, perhaps mostly for historical reasons, all possible z-scores from negative infinity to positive infinity have meaning in statistical theory and practice.
That's called scratch

Integers are any whole number, positive or negative, including 0. An example of integers used in the world would be sports game scores, as no one ever scores a fraction of a point.
In general, the answer is no, both negative and positive z score values should be expected. A z-score (or standardize score) is the raw data value minus the mean and then this result divided by the standard deviation. If the data can be considered normally distributed and a random sample is taken from a population, then as the sample size becomes large, approximately half the z-scores should be negative and half of the z-scores should be positive. There are some exceptions. Small data sets may have only positive values. A non-normal (skewed) distribution if skewed to the right, may have, after normalizing, may have a higher portion of z scores as positives.
Normally pacer scores are not counted or are specially marked in league software using a P with CDE Software's Bowling League Secretary software.
That's called a hook. Developing a good one is essential to getting the best scores, and the most fun from bowling.
