The average is sensitive to individual very large values. The median shows the middle of an ordered sample and helps reveal the typical level. To evaluate a channel, it is useful to look at both metrics together with the number of posts and the measurement conditions.

A set of five publications
Training views: 100, 110, 120, 130 and 1 000. The sum is 1 460, the average is 292, the median is 120. Four of the five posts received less than the average, so the phrase "a typical post gets about 292" creates a false expectation.
Load these values into a statistics analyzer with the columns name and views. The tool will show both totals. Then examine the large post separately: its topic, pinning, external distribution and observation time may have differed. A large value does not need to be automatically deleted as an error.
When the comparison is valid
Collect views after the same amount of time following publication. Comparing three days of a new post with all views of an old post over a year answers a different question. Separate formats and special placements if they differ substantially.
For an even number of posts, the median is the average of the two central values after sorting. If some views are unknown, they do not become zero: the report has a separate count of known rows. Five observations cannot confidently describe the coming month.
How to use the conclusion
In the media kit, label it "the median of five posts after 48 hours" or "the average of the entire series over the selected window." For ad planning, add a cautious scenario to the media plan, keeping the source of the assumption. Do not use only the maximum as the promised result of a typical placement.
If you compare two periods, keep the same rules for including posts. A rise in the median shows a change in the sample, but does not prove that advertising was the cause: topics, frequency and external demand could have changed at the same time. A chart helps find questions to check, rather than replacing an explanation of causes.
If a separate public announcement in Telegram has been prepared for this work, you can check the current views terms. The analyzer works with your CSV and does not confirm the origin of the activity. Purchased activity does not confirm organic interest, recommendations, leads, or sales.
