I have a point layer with standard deviation values and i want to get the average value of points in a 1 square-kilometer raster. I used the rasterize tool from QGIS to make a raster but this tool uses only one value of all points that lay in the raster.
Is it possible to do this?

You could try the Zonal Statistics Plugin
Create polygon layer with a 1x1 km vector grid (Vector -> Research Tools -> Vector Grid) and run the zonal statistics plugin.
It will add serveral attribute to each cell polyogon - like minimal, maximal, median, sum, stdev, ... values of the contained raster cells.
