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 set.

5. The mean is always the best measure of central tendency to use.

These are the answer choices for each question:

False. The range is a value representing the difference between the maximum and minimum value and tells us nothing else about the data set.

False. If there is an outlier or extreme value then the mean will be pulled in the direction of the outlier and not be a good representation of data.

False. The mean is the average of all the values so it is not necessarily a data value.

False. There could be a situation where there is no mode.

True. The range represents the difference between the largest and smallest value so it shows the spread of data, hence variability.

False. The there could two values in the middle and you would have to find the average of the two values and therefore the median would not be a data value.

True. Since the mean is the average of the data values it is always the best value to use when representing the data.

True. If the median is the value in the middle and you are dealing with an ODD number of data values then the median will be the data value in the middle.

True. If there is a mode then it will be one of the data values since it is the data value that shows up the most.

True. The mean is the average of the data values so it must be one of the values

1. The mean is always one of the data values.

False

Data: 3, 5, 9

Mean = (3+5+9)/3 = 5.67 which is not in the data values.

2. The median is always one of the data values

False

Data: 3, 5, 6, 8

Median = (5+6)/2 = 5.5 which is not in the data values.

3. The mode is always one of the data values.

False

Data: 3, 5, 6, 8

There is no mode in the data.

4. The range measures the variability of the given data set.

True

5. The mean is always the best measure of central tendency to use.

False

Data: Male, Female, Female

The best measure of central tendency to use for this data is the mode.

Please give me a thumbs-up if this helps you out. Thank you!
