Question

Flight 4581 travels daily from Pittsburgh to San Antonio. The flight is due into San Antonio at 5:07 p.m. The following list gives the Flight arrival time relative to p.m. (in minutes) for a selection of days. (A negative number means that the flight arrived early.)

-5,-4,-4,-3,-2,2,2,3,4,5,6,6,6,11,17,25,26,36

(a) For these data, which measures of central tendency take more than one value? Choose all that apply.

Mean

Median

Mode

None of these measures

(b) Suppose that the measurement -5 (the smallest measurement in the data set) were replaced by -22. Which measures of central tendency would be affected by the change? Choose all that apply.

Mean

Median

Mode

None of these measures

(c) Suppose that, starting with the original data set, the largest measurement were removed. Which measures of central tendency would be changed from those of the original data set? Choose all that apply.

Mean

Median

Mode

None of these measures

(d) The relative values of the mean and median for the original data set are typical of data that have a significant skew to the right. What are the relative values of the mean and median for the original data set? Choose only one.

Mean is greater

Median is greater

Cannot be determined

Seeing if i did these right
What is the goal of central tendency?
The goal of central tendency is to
find the “middle” of a distribution. It identifies one single
measure that best describes a set of data
Find the mean, median, and mode for
the following sample of scores: 5, 4, 5, 2, 7, 1, 3, 5
Mean________4_______
Median_______4.5________ Mode_______5________
Find the mean, median, and mode for the following sample of
scores: 3, 5, 7,, 3, 9, 8, 3,...

A researcher has conducted a study and has obtained a data set.
He is seeking your help and requests that you calculate the mean,
range, median, and mode and distinguish which of these are measures
of central tendency and which are measures of variability.
Additionally, he has calculated the variance and standard
deviation, and would also like you to classify these measures. He
thanks you in advance for your help. The data set is as follows:
14, 10, 9, 16,...

Answer True or False for each of the following. If your answer
is FALSE, provide an example that proves your point. If your answer
is true, explain. Given a typical set of numerical data with an ODD
number of values.
1. The mean is always one of the data values.
2. The median is always one of the data values
3. The mode is always one of the data values.
4. The range measures the variability of the given data...

Which one of the following is always true?
Select one:
a. The coefficient of variation measures variability in a
positively skewed data set relative to the size of the median.
b. None of the suggested answers are correct
c. The coefficient of variation is a measure of relative
dispersion that expresses the standard deviation as a percentage of
the mean, for any data on a ratio scale and an interval scale.
d. The interquartile range is very unique in the...

1. Which of the following statements is correct?
a. The median can be strongly influenced by just one or two
very low or high values.
b. The mode gives equal consideration to even very extreme
values in the data.
c. There will be just one value for the mean, median , and mode
in the data set.
d. The mean is able to make the most complete use of the data
when compared to the median and mode.
e. None...

location)?
True
False
2,The mean computed from ungrouped data is a more accurate measure
than the mean computed from grouped data?
