Efficiency analysis of received balls by UrSU team in one game

Ball serving types	Total number of balls during one game	Results of received balls
		Exactly received balls	Lost balls	Efficiency %
Simple serving from standing position	13	13	-	100
Oscillatory movement	21	18	3	85.7
Jump serving with one or two steps	16	13	3	81.2
Jump serving with force	13	9	4	69.2
Total	63	53	10	84.1

Comparing the efficiency of received balls by UrSU team before and after the analyses we have observed the following results:

The total number of balls using simple serving from standing position before the research is – 10, after the research is – 13, exactly received balls before the research are- 7, after the research are – 13, lost balls before the research are – 3, no lost balls after the research, efficiency before the research is – 70%, efficiency after the research is – 100%.
The total number of balls using oscillatory movement before the research is – 28, after the research is – 21, exactly received balls before the research are – 15, after the research are – 18, lost balls before the research are – 13, after the research are – 3, efficiency before the research is – 53.5%, efficiency after the research is – 85.7%.
