Which measure of central tendency is best worksheet?
If all the numbers in a set of data are relatively close together, either the median or mean can be used as a measure of central tendency. If a data set contains unusually large or small numbers relative to the rest of the data, the median is usually the best measure of central tendency.
What are the examples of measures of central tendency?
Measures of central tendency are numbers that tend to cluster around the “middle” of a set of values. Three such middle numbers are the mean, the median, and the mode. For example, suppose your earnings for the past week were the values shown in Table 1.
Which of the following is the best measure of the central tendency for confidence in education?
The mean
The mean is generally considered the average score and is considered the best measure of central tendency, unless exaggerated by extreme scores.
How do you choose a measure of central tendency?
Here are some general rules: Mean is the most frequently used measure of central tendency and generally considered the best measure of it….Median is the preferred measure of central tendency when:
- There are a few extreme scores in the distribution of the data.
- There are some missing or undetermined values in your data.
What is meant by measures of central tendency answer?
In statistics, a central tendency (or measure of central tendency) is a central or typical value for a probability distribution. Colloquially, measures of central tendency are often called averages. The term central tendency dates from the late 1920s.

Measures of central tendency help you find the middle, or the average, of a data set. The 3 most common measures of central tendency are the mode, median, and mean. Mode: the most frequent value. Median: the middle number in an ordered data set. Mean: the sum of all values divided by the total number of values.
What are the most common measures of central tendency?
Mean. Mean is an approach that is generally used in Statistics.
How do you calculate central tendency?
If you have a symmetrical distribution of continuous data,all the three measures of central tendency hold good.
What is an example of a measure of central tendency?
– There are few extreme scores in the distribution. – Some scores have undetermined values. – There is an open ended distribution. – Data are measured in an ordinal scale. – Mode is the preferred measure when data are measured in a nominal scale. Geometric mean is the preferred measure of central tendency when data are measured in a logarithmic scale.[8]
What is the measurement of central tendency?
Median. The median is the middle score for a set of data that has been arranged in order of magnitude.
