The score is a z-score with the average score being 0. It tells you how many state standard deviations your grade or individual student’s MCA-II strand score is away from the state average. Difference indexes of greater than .5 or less than -.5 should be seen as meaningful and examined further.

how you find it on the Z-table. Draw the normal curve and shade. What is a critical value for z for a 90% confidence interval? Draw. the normal curve and shade. Why is the z-value 1.96 while in the previous sections we used plus or minus 2 standard deviations for the “pretty sure” measure? Do the “Just Checking” on page 445.

There are three approaches to getting a p-value for this problem. First, we can use the z-table as an approximation, knowing that it will always under-estimate the p-value for a t-test. In the z-table we get a value of 0.1179, which implies a two-tailed p-value of . 2*(0.5 – 0.1179) = 0.7642. Another way to go is to use a special t-table, such as

Since these electrons are being placed in the same energy sublevel, their contribution to shielding is limited (Slater 0.35), thus the greater number of protons (Z increase by 1 for each element) results in greater force of attraction The electrons respond by shifting closer to the nucleus.
