BESC 3010 Exam 1 Questions and
Correct Answers
Nominal level of measurement - Answer-characterized by data that consist of names, labels, or
categories only, and the data cannot be arranged in an ordering scheme (such as low to high)
ordinal level of measurement - Answer-a measurement of a variable in which the numbers indicating a
variable's values specify only the order of the cases, permitting greater than and less than distinctions
interval level of measurement - Answer-A measurement of a variable in which the numbers indicating a
variable's values represent fixed measurement units but have no absolute, or fixed, zero point
ratio level of measurement - Answer-possesses all the characteristics of interval measurement, and
there exists a true zero. In addition, true ratios exist when the same variable is measured on two
different members of the population.
categorical levels of measurement - Answer-nominal and ordinal
Quantitative levels of measurement - Answer-interval and ratio
, bar chart - Answer-A form of graph in which numeric values are represented by horizontal or vertical
rectangles.
Histogram - Answer-A graph of vertical bars representing the frequency distribution of a set of data.
box plot - Answer-A graph that displays the highest and lowest quarters of data as whiskers, the middle
two quarters of the data as a box, and the median
unimodal distribution - Answer-frequency distribution with one value clearly having a larger frequency
than any other
bimodal distribution - Answer-a frequency distribution having two different values that are heavily
populated with cases
positive skew - Answer-high outlier
negative skew - Answer-low outlier
Kurtosis - Answer-how flat or peaked a normal distribution is
Platykurtic distribution - Answer-A less peaked distribution that indicates that more returns with large
deviations from the mean have occurred, or are expected to occur, than with a normal distribution. (Plat
is Flat).
mesokurtic distribution - Answer-Having a normal bell shaped curve; a normal distribution of scores
Leptokurtic distribution - Answer-A more peaked distribution that indicates that more returns are
clustered around the mean than with a normal distribution. (Lepto=Less Risky)
