A sample of n=4 scores has a mean of 75. What is the z score of the sample? Z-Scores: Z-scores are used to determine where a score or sample falls within a distribution relative to the mean of that distribution, in terms of the variability of that distribution. ...
2. Nice properties in ANOVA such as the Grand Mean being the intercept in an effect-coded regression model don’t hold when data are unbalanced. Instead of the grand mean, you need to use a weighted mean. That’s not a big deal if you’re aware of it. But there are a few real ...
The threshold score was the mean of the last four turning points in the staircase, with the final score ranging between 1 and 16 points. The discrimination task used the same 3 AFC logic. Two pens of any triplet contained the same odorant, while the third pen smelled differently. Subjects ...
. Following the author’s recommendations, we computed a composite mean score by multiplying each concern-of-rejection rating with the inverse of the corresponding expectancy-of-acceptance rating, taking the mean of the resulting scores. Higher composite scores indicate higher rejection sensitivity. Inte...
18. Poor quality diets were defined as diets either having a high mean excess ratio (highest third of the population) or a low nutrient efficiency score (NRF9.3) (lowest third of the population). A true poor quality diet would be a combination of high MER and low MAR values, however ...

This tool calculates the z-score of the mean of a single sample. It can be used to make a judgement about whether the sample differs significantly on some axis from the population from which it was originally drawn. By default, this tool works on the assumption that you already know the ...

.99/2 = 0.495. The closest z-score for 0.495 is 2.58. Step 2:Multiply step 1 by the standard deviation. 2.58 * 2.9 = 7.482 Step 3:Divide Step 2 by the margin of error. Our margin of error (from the question), is 0.5.
