Let us solve some interesting problems using the mean median mode formula. Measures of central tendency are measures of location within a distribution. The Mean Median and Mode are the three measures of central tendency.

Which is Best the Mean Median or Mode. However if you have a skewed distribution the median is often the best measure of central tendency. The difference between the largest and smallest data is the range.

The mean is the only measure of central tendency where the sum of the deviations of each value from the mean is always zero. As already discussed the mean median and mode are known as measures of central tendency. The mean median and mode are all valid measures of central tendency but under different conditions some measures of central tendency become more appropriate to use than others.

Mode median or mean. When you have a symmetrical distribution for continuous data the mean median and mode are equal. The median is the middlemost value in the ordered list of observations whereas the mode is the most frequently occurring value.
