1. What type of variable is "Hierarchical Level" composed of the fields 'Junior Associate', 'Associate', 'Senior Associate', 'Associate Partner', and 'Partner'?

2. What is an appropriate measure of spread for the variable "Hierarchical Level" described in the previous question?

3. If you have a normally-distributed variable with a mean of 52 and a standard deviation of 30 then we may expect roughly_________ (how much?) of the data to lie between the values and ____________.

4. If you have a median of 1,200 and an inter-quartile range of 550 then which of the following is true:

-Approximately two-thirds of the population is expected to lie between 650 and 1750

-The data are inaccurate

-if you go 550 above 1200 then you have increased by one standard deviation

-Approximately half of the data lie between 650 and 1750

-The variable runs from a low of 40 to a high of 160

-The standard deviation lies between 650 and 1750

-The variance of the variable is 900

5. Say you have a variable that lies roughly between 0 and 100. Most of the data lies between 0 and 30, with increasing probability from 0 to 15 and decreasing probability from 15 towards 30. There are also increasingly rare data points as one goes from 30 to 100. What sort of distribution is this?

Group of answer choices -Unimodal

Bimodal

Lognormal

Normal
