Runs per Over (Economy Rate) : Total Runs conceded in an Over.
From Bowler’s perspective, extras (byes and leg byes) are not counted as run, hence not added to his tally of runs conceded in an over, but error balls (noballs and wides ) are counted and added to his over, which is displayed in his bowling figure.
From Team’s perspective, apart from scoring shot, all extras should be counted as run, and added for analysis purpose….
A Run is a run !! it decides fate of the match.

Inns : 4
Overs (Balls) 120.5 (725)
Wickets : 12
Runs / Over = 344 /120.5 = 2.84
From batting perspective: This indicator should only be used for team’s measurement, and not for individual batsman. It would be wrong to analyse from batting point of view, because one batsman never faces every ball of an over in an inning/match or series, so how can you measure his runs/over?.
Currently an over constitutes 6 balls, and one batsman might face few in one over, but never all of them in an inn or a match.
E.g G Bailey in 4th ODI scored 87 runs facing 91 balls, he came into bat when score was 3/51 (15.1 overs), & when he got out the score was 9/218(45.2over) viz he was at the crease for 32.3overs(195balls), facing 91 balls only.
