Q
Descriptive statistics
A
Summarizes important data descriptions
2
Q
Inferential statistics
A
Observing a small group then forecasting a large group
3
Q
Population
A
All members of a specified group
4
Q
Sample
A
A subset of the population
5
Q
Measurement Scales
A
Nominal, Ordinal, Interval, Ratio
6
Q
Nominal
A
Mutual funds: Groups but no rank
7
Q
Ordinal
A
Mutual Fund Performance: Observations are ranked, differences are not equalized
8
Q
Interval
A
Temperature: Rank and differences between scale values are equal but no true zero point exists
9
Q
Ratio
A
Money, rates of return: Ranked, and differences between scales are equal and a true zero point exists.

a distinguish between descriptive statistics and inferential statistics, between a population and a sample, and among the types of measurement scales;0
-
b define a parameter, a sample statistic, and a frequency distribution;0
-
c calculate and interpret relative frequencies and cumulative relative frequencies, given a frequency distribution;0
-
d describe the properties of a data set presented as a histogram or a frequency polygon;0
-
e calculate and interpret measures of central tendency, including the population mean, sample mean, arithmetic mean, weighted average or mean, geometric mean, harmonic mean, median, and mode;0
-
f calculate and interpret quartiles, quintiles, deciles, and percentiles;0
-
g calculate and interpret 1) a range and a mean absolute deviation and 2) the variance and standard deviation of a population and of a sample;0
-
h calculate and interpret the proportion of observations falling within a specified number of standard deviations of the mean using Chebyshev’s inequality;0
