2-1 Smart book Assignment: Chapter 3
- Sorting data is helpful because:
Answers
we can see the frequency of each data value.
we can see the range of values.
- A stem-and-leaf plot is basically:
Answers
a tool which uses the digits in each number to create stems and leaves.
a tool used in exploratory data analysis.
a frequency tally.
- True or false: A dot plot displays individual values of qualitative data.
Answer
False
- When constructing bins for a frequency distribution of quantitative data, which of the following
principles should generally be followed?
Answers
Bins should be the same width.
Bins should be mutually exclusive.
The bins should be exhaustive.
- If the data were collected from a random sample we must allow for SAMPLING error
Answers
A relative frequency distribution for quantitative data identifies
the proportion of observations that occur in each bin.
- Which type of data cannot be sorted?
Answer
Nominal
- Stem-and-leaf displays can be used to
Answers
determine central tendency and dispersion.
analyze the small samples of integer data.
observe individual data points.
- The rectangles of a histogram
Answers
Represents grouped data are drawn with no space, or gaps, between them, except when there is
no data in a particular bin.
Represent the class width and frequency, or relative frequency, of the respective class
- Dot plots can show which features of a data set?
Answers
Variability
Shape
Center
- One of the primary goals of constructing a frequency distribution for quantitative data is to
Answers
summarize the data by showing frequency of values that lie within a class or bin.
