Chapter 5: Q. 72 (page 352)

Consider the following experiment. You are one of 100 people enlisted to take part in a study to determine the percent of nurses in America with an R.N. (registered nurse) degree. You ask nurses if they have an R.N. degree. The nurses answer “yes” or “no.” You then calculate the percentage of nurses with an R.N. degree. You give that percentage to your supervisor. a. What part of the experiment will yield discrete data? b. What part of the experiment will yield continuous data

Short Answer

Expert verified

a. Responses of experiment can yield discrete data.

b. Supervisor collecting can yield continuous data.

Step by step solution

01

Theory of discrete data

Discrete data can be yielded through response of survey to understand publics information.

02

Theory of continues data

Continues data can be yielded by collecting all information from the nurse who have R.N degree. Due to this reason, Supervisor collecting is important for continuous data.
