What to Focus On
- Measures of central tendency are also known as statistical averages.
- They include mean, median, and mode.
- They give a single representative number for a data set.
- Mean is the value derived by summing all values and dividing by the number of observations.
- The mean is a measure of central tendency.
- For ungrouped and grouped data, the methods are different.
- Median is a positional average.
- It divides an arranged series into two equal parts.
- It is independent of the actual value.
Common Mistakes to Avoid
Mean, median, and mode are just three names for the same kind of average.
Mean can be found in the same way for ungrouped and grouped data.
The indirect method of mean works only for equal class intervals.
