Is median a measure of central location?
Yes, the median is a measure of central location. It represents the middle value of a data set when the values are arranged in ascending or descending order. The median effectively divides the data into two equal halves, making it a useful measure, especially in skewed distributions where it provides a better central tendency measure than the mean.
If a data set has many outliers which measure of central tendency would be the BEST to use?
In a data set with many outliers, the median is the best measure of central tendency to use. Unlike the mean, which can be significantly affected by extreme values, the median provides a more accurate representation of the central location of the data. It effectively divides the data into two equal halves, making it robust against outliers. Therefore, the median offers a clearer understanding of the typical value in such cases.
Which measure of central location will the sum of the deviation of each value from the data's average will always be zero?
the mean %100
What is the sum of all deviations of a data value from a measure of central location that will always be zero?
Difference (deviation) from the mean.
What is statistical average?
average is defined as a single value which has tendency to represent the data as a whole. averages are also called "measure of central tendency" or "measure of location"

A value that is typical or representative of the data is referred to as a measure of central location?
No, it is not, values typical of the data are always located at the extremes of all data frequencies.
For which measure of central location will the sum of the deviations of each value from the data's average will always be zero?
The mean.
Which measure of central location will the sum of the deviations of each value from the data's average always be zero?
the mean
Which measure of central location is found by arranging the data from smallest to largest and selecting the middle value?
median

Difference (deviation) from the mean.
Which measure of central tendency can be calculated for both quantitative data and for qualitative data?
Mode is the only measure of central tendency to measure quantitative dataor qualitative data.

What kind of conclusions could you make about box and whisker plots?
It is a useful scheme to summarise data. It provides information on the central tendency (median) and a measure of spread (inter-quartile range). The total range is also indicated and outliers are separately identified. The location of the median within the IQR "box" provides an indication of the skewness of the data.
Which measure of central tendency is the most accurate measure of data?
That depends on the data.
