EXPERTLY VERIFIED ANSWERS.
1. Skewed to the left - correct answer -the mean is typically lower
than the median
2. Skewed to the right - correct answer -the mean is typically
greater than the median.
3. Time/Trend plot - correct answer -displays values against time.
4. Outlier - correct answer -an observation point that is distant
from other observations.
5. Resistant - correct answer -statistics don't change (or change a
tiny amount) when outliers are added to the mix.

6. Range - correct answer -The difference between the lowest
and highest values.
7. Standard deviation - correct answer -a quantity calculated to
indicate the extent of deviation for a group as a whole.
8. Variance - correct answer -measures how far a set of (random)
numbers are spread out from their average value.
9. Empirical Rule - correct answer -states that for a normal
distribution, nearly all of the data will fall within three standard
deviations of the mean.68% of data falls within the first
standard deviation from the mean. 95% fall within two standard
deviations.99% falls within 3 standard deviations of the mean.
10. Quartiles - correct answer -each of four equal groups into
which a population can be divided according to the distribution
of values of a particular variable.
11. Interquartile range (IQR) - correct answer -measure of
variability, based on dividing a data set into quartiles.
