When exploring median vs mean, it's essential to consider various aspects and implications. outliers - Trimmed mean vs median - Cross Validated. My guess is a median / 50% trimmed mean is much more aggressive than is necessary for your data, and is too wasteful of the information available to you. If you have any sense of the proportion of outliers that exist, I would use that information to set the trimming percentage and use the appropriate trimmed mean. Which is better, replacement by mean and replacement by median?.
This perspective suggests that, replacement by mean or median --- or mode -- is in effect saying that you have no information on what a missing value might be. It is hard to know why imputation is though to help in that circumstance. sample size - When to use mean or median? 2 When the mean and the median are different, data distribution is said to be skewed. Moreover, in the example you mentioned, the median (162) is larger than the mean (129), which means there are more observations towards larger values than towards smaller ones.
Median-based Versus Average-based forecast? 4 When generating forecasts (e.g., product-customer time series data), should we choose an average-based forecast or median-based forecast? I recently read a very nice article by Nicholas Vandeput on LinkedIn wherein he linked the forecast type to use of different best fit selection criteria.
Furthermore, how does the expected value relate to mean, median, etc. Ok, so the question should technically be "how does the expected value relate to the mean, median etc. of data drawn randomly from a particular probability distribution?" I'm looking for simple, intuitive understandings, similar to the way you can intuitively say that when a distribution is more skewed, the median and the mean are further apart, and the median may give a better indication of ... Why is median age a better statistic than mean age?.
People of such age have 1.5 to 4 times the influence on the mean than they do on the median compared to very young people. Thus, the median is a bit more up-to-date statistic concerning a country's age distribution and is a little more independent of mortality rates and life expectancy than the mean is. Quantitative rule for reporting mean (SD) vs. A general rule of thumb for reporting mean or median as the defining measure of central tendency is a function of skewness. In a normally distributed distribution (with skew more or less between -1 and 1), the mean is the best measure of central tendency. Median Absolute Deviation vs Standard Deviation - Cross Validated.
Many of the comments in posts about using variance rather than mean absolute deviation from the mean (e.g. here) apply also to median absolute deviation from the median. Similarly, clustering - k-means vs k-median? Another key aspect involves, i know there is k-means clustering algorithm and k-median.
One that uses the mean as the center of the cluster and the other uses the median. My question is: when/where to use which? Another key aspect involves, comparison of distribution mean or median - Cross Validated. As above, trimmed calculations can be more stable than the mean or median, see measures of location.
📝 Summary
