Question

What is a centrel tendency

Answer 1

Answer:

Central tendency is a statistical measure used to identify a single value of the entire population or a dataset, it reflects the center of data distribution. It was first coined in the 1920s.

• It is one of the most important and basic elements of statistics.
• It is comprehensive.

• It does not provide the data on an individual data set but as a whole.

Central tendency consists of the following measures such as :

1. Mean: It represents the sum of the whole data set divided by the total number of values.
2. Median: It represents the middle value in an arranged set of data.

           Note: The data must be arranged in either ascending or descending order.

     3. Mode: It represents the maximum number of times occurring value in a data set.

There are more tools in central tendency like geometric mean, harmonic mean, mid-range, and geometric median.

• Explanation: The reason we use central tendency is as follows:-

1. It is easy to obtain and less complex in nature
2. It serves as a basis for all the statistical tools.
3. Mean is a good option for ordinal sets of data.
4. It is more resistant to change and not flexible in nature.
5. One can make use of all the data available in the set.
