SIMPLEST TRICK TO UNDERSTAND CENTRAL TENDENCY?
Answers
in statics mean is known as average for eq there are 1 2 3 4 5 ,,,,,,,,,, n numbers
then mean =sum of all numbers / total number which are in sample space so here mean is
mean = (1+2+3+..........n)/n
now for median
Use the median to describe an entire set of observations with a single value representing the center of the data. Half of the observations are above the median, half are below it. It is determined by ranking the data and finding observation number [N + 1] / 2. If there are an even number of observations, the median is extrapolated as the value midway between that of observation numbers N / 2 and [N / 2] + 1.
For this ordered data, the median is 13. That is, 50% of the values are less than or equal to 13, and 50% of the values are greater than or equal to 13.
for mode
ModeThe mode is the value that occurs most frequently in a set of observations. Minitab also displays how many data points equal the mode. Mode may be used with mean and median to give an overall characterization of your data distribution. While the mean and median require a calculation, the mode is found simply by counting the number of times each value occurs in a data set.
for
Trimmed MeanThe trimmed mean is the mean of the data, without the highest 5% and lowest 5% of the values. Use the trimmed mean to eliminate the impact of very large or very small values on the mean. When the data contain outliers, the trimmed mean may be a better measure of central tendency than the mean.these are the concepts of central tandency
