The Wesleyan study looks at the number and frequency, but not the depth to which political attacks have sunk.
Not only are fewer people smoking, but among people who smoke, the frequency has plummeted.
On top of all that, the frequency of climate shocks seems to be rising.
Dr. Greenberg also indicates that the frequency of splurges can change depending on where you are in relation to your goal.
There is also the question of the frequency of major new decisions.
It was only years later that the ones in the smaller compartment had been adjusted to the other frequency.
The amount and frequency of the whiskey for consumption in this country were astonishing.
They have also crossed occasionally in the spring, but without any regularity or frequency, and generally in very small parties.

1640s, "fact of occurring often," from Latin frequentia "a crowding, crowd," from frequentem (see frequent).
Earlier it had been used in a now-obsolete sense of "state of being crowded" (mid-16c.); sense in physics, "rate of recurrence," especially of a vibration, is from 1831. In radio electronics, frequency modulation (1922, abbreviated F.M.) as a system of broadcasting is distinguished from amplitude modulation (or A.M.).
In physics, the number of crests of a wave that move past a given point in a given unit of time. The most common unit of frequency is the hertz (Hz), corresponding to one crest per second. The frequency of a wave can be calculated by dividing the speed of the wave by the wavelength. Thus, in the electromagnetic spectrum, the wavelengths decrease as the frequencies increase, and vice versa.
