The result of that division is the Z score of the chosen sample, indicating how many
Mean, Median, Mode, and Range
Mean, median, and mode are three kinds of "averages". There are many "averages" in statistics, but
these are, I think, the three most common, and are certainly the three you are most likely to encounter in
your pre-statistics
Calculating T-Scores:
T-Scores: have an average of 50 and a standard deviation of 10. Scores above 50 are above
average. Scores below 50 are below average.
T-scores are calculated using this formula: t = 10(z-score) + 50
Step 1: Calculate the z-score. The
CALCULATING STANDARD DEVIATION WORKSHEET
The standard deviation is used to tell how far on average any data point is
from the mean. The smaller the standard deviation, he closer the scores are
on average to the mean. When the standard deviation is large,
