I have the huge number of points spread across some map.
Is it possible to calculate the mean value of a parameter in the points of a small area and make one point for the same so that the total number of points in the map can be reduced?

One tool available in QGIS processing toolbox is SAGA Points thinning tool (in
Processing toolbox | SAGA | Vector point tools).
When activated, you will find two input parameters to set:
It returns a
Thinned Points layer, and its attribute table has the mean (among other parameters = count, mean, min, max, sd) of the value you chose for
Hope it helps.
