It is to determine whether a
concrete has the specified compressive strength
Compression test
the root mean square of the
deviations about the arithmetic mean of a set of
values.
Standard deviation
it is sum of scores divided by the number of
cases.Popularly known as the average.
Mean
It is the middle number of a set of numbers arranged in order

Mode
Source of error in taping when tape may differ in actual length from its nominal graduated length because of a deflect in manufacture or repair

Natural error

Personal ERROR
Defined as a number of vehicle passing a point on highway or given lane or direction of a highway in specific time
Volume
Generally expressed in units of veh/hr but represents the flow thst exists for period of time less than an hour
Rate of flow
Average speed of all vehicles passing a point over a specified time period
Time mean speed
Average speed of all vehicles occupying a given dection of roadway over a specific time period
Space mean speed
Number of vehicles occupying a road lane per unit length of a given instant in time
Density
Maximum sustained 15 min flow rate, expressed in passenger cars per hr per lane
Capacity
Used to define two or more points that lie on the same line
