In the variable distribution sequence, frequency indicates the function degree of the corresponding group flag values. The greater the frequency value, the greater the contribution of this group of flag values to the overall level; On the contrary, the smaller the frequency value, the smaller the contribution of this group of marker values to the overall level.
Question 2: What does frequency mean in mathematics? Frequency?
Under the same conditions, n experiments were carried out. In these n experiments, the frequency m of event A is called the frequency of event A. ..
The ratio m/n is called the frequency of event A, and is defined as the ratio of the number of occurrences of each object to the total number of occurrences.
The ratio of the frequency of a population to the sample size is also called the frequency of this population. With frequency (or frequency), we can know the distribution of numbers.
Question 3: What is the frequency in mathematics? Frequency is the number of times to complete vibration per unit time, and it is a quantity to describe the reciprocating motion frequency of vibrating objects. It is usually represented by the symbol f or v, and the unit is-1. In order to commemorate the contribution of German physicist Hertz, people call the unit of frequency Hertz for short. Every object has a frequency independent of amplitude, which is determined by the nature of the object itself and is called the natural frequency. The concept of frequency is not only used in mechanics and acoustics, but also in electromagnetism and radio technology. The number of times that alternating current completes periodic changes in unit time is called the frequency of current.
