Occurrence

At least one batter is not out at the end of every innings, because once ten batters are out, the eleventh has no partner to bat on with so the innings ends. Usually two batters finish not out if the batting side declares in

Batters further down the batting order than the not out batters do not come out to the crease at all and are noted as ''did not bat'' rather than ''not out''; by contrast, a batter who comes to the crease but faces no balls is ''not out''.

Notation

In standard notation a batter's score is appended with an asterisk to show the not out final status; for example, ''10*'' means '10 not out'.

Impact on batting averages

Batting averages are personal and are calculated as runs divided by dismissals, so a player who often ends the innings not out may get an inflated batting average, on the face of it. Examples of this include MS Dhoni (84 not outs in ODIs),

topping the batting averages on the 1953 Australian tour of England. Using the formula of runs divided by innings understates performance for the following reasons: *If not outs were counted as dismissals a usually high-scoring batter could bat briefly. They may regularly make a low score, not out, facing a low number of balls from a bowler and thus be penalized for factors out of their control. *A batter will tend to be at their most vulnerable early in the innings before they have "got their eye in"; as a result, it may be a greater achievement to achieve two scores of 20 not out (i.e. averaging 40) than to make one score of 40, since in the latter instance the batter will only have had to deal with one set of variables (see ceteris paribus, all things remaining approximately equal). These counterbalancing elements have been at the heart of the rationale of keeping the existing formula (runs divided by dismissals) in the 21st century among cricket statisticians, who have used this method of collecting batting averages since the 18th century, after some intervening controversy.
