Multiple Choice Quiz:
What is the median and what’s the first step to find it?
Most frequent occurring data value and is found by putting the data values in numerical order
Middle observation in an ordered data list and is found by putting the data values in numerical order
Middle observation in an ordered data list and is found by putting the data values in random order
Most frequent occurring data value and is found by putting the data values in random order
Which of the following best describes the mode?
Most frequent occurring data value. If every data value has the same frequency, the data set has no mode
Middle observation in an ordered data list. If every data value has the same frequency, the data set has no mode
Most frequent occurring data value. If every data value has the same frequency, you will find the data’s mode
Middle observation in an ordered data list. If every data value has the same frequency, you will find the data’s mode
What is the Mean and how can it be found?
The arithmetic average and is found by adding all the data values, then dividing that sum by the number of data values
The arithmetic average and is found by adding all the data values, then multiplying that sum by the number of data values
The arithmetic average and is found by subtracting all the data values, then dividing that sum by the number of data values
Most frequent occurring data value and is found by subtracting all the data values, then multiplying that sum by the number of data values
Which of the following best describes standard deviation?
A measure of the “typical” deviation from the median for the values in the data set
The “typical” deviation, square all numbers in a data set, divide by the amount of numbers in the data set and subtract the mean square, square root the number
A measure of the “typical” deviation from the mean for the values in the data set
A numerical value used to indicate how widely individuals in a group vary
According to topic 17 and your pre-existing knowledge, a normal curve is referred to as
Bell curve
Ideal curve
Gaussian curve
Probability curve
The best answer that describes the basic characteristics of a normal curve is
All of the observations lie above the horizontal axis and under the curve
The curve practically touches the horizontal axis at the two points on the horizontal axis that are located three standard deviations from the mean
The peak occurs above the value on the horizontal, corresponding to the mean of the data set. The curve is symmetric with respect to the mean. The curve changes concavity above the two points on the horizontal axis located one standard deviation from the mean
None of the above
What does the z-score tell us?
How many standard deviations the observed data value lies away from the mean
Exact amount of standard deviations in the observed data
The predicted amount of deviations observed in the data value that lies away from the media
How many deviations the observed data value lies away from the reason
What term best defines range?
The subtraction of the maximum and minimum number from the data
The difference between the maximum data value and the minimum data value
Both A and B
None of the above
According to topic 16.3 in WileyPLUS, which of the following best describes interquartile range?
Length of the middle half of the data and is found by first identifying the first and fourth quartiles of the data
Length of the lower half of the data and is found by first identifying the first and second quartiles of the data
Length of the middle half of the data and is found by first identifying the first and third quartiles of the data
Length of the middle half of the data and is found by first identifying the first and second quartiles of the data
What answer best describes first quartile (Q1) and third quartile (Q3)?
The first quartile (Q1), is the median of the lower half of the data values. The third quartile (Q3), is the median of the upper half of the data values. This involves finding two additional medians.
The first quartile (Q1), is the median of the lower half of the data values. The third quartile (Q3), is the median of the upper half of the data values.
The first quartile (Q1), is the median of the upper half of the data values. The third quartile (Q3), is the median of the lower half of the data values.
Both A and B
Which of the following best describes the five-number summary?
List the first and third quartiles, together with the median and the minimum and maximum data values
Listing the quartiles, with the median and the minimum and maximum data values
List the first and third quartiles, together with the mode and the minimum and maximum data values
Listing the quartiles, together with the mode of the maximum data value
