Question

Which of the following describe discrete data?
(select all that apply)
a. The exact foot lengths (measured in cm) of a random sample of statistics students.
b. The exact times that randomly selected drivers spend texting while driving during the past 7 days.
c. The numbers of people surveyed in each of the next several years for the National Health and Nutrition Examination Surveys.

Answer 1

Answer:

Option C

Step-by-step explanation:

The discrete data is the one in which data values are countable and the continuous data is the one in which data values can't be counted but can be measurable.

The exact foot length and exact time cannot b counted but can be measured. For example foot length can be 13.8 cm and exact time can be 8:25 etc. So, both of these variables belongs to continuous data.

The number of people involved in survey can be counted and so it depicts discrete data.
