What is quality fluctuation? It refers to the phenomenon in the production process where the property values of products are not entirely consistent. Including normal fluctuations and abnormal fluctuations.

Fluctuations in product quality characteristics refer to the uneven variation in the value of these characteristics.
Quality fluctuations are a type of variation that can be divided into two categories: normal fluctuations and abnormal fluctuations. Quality fluctuations are divided into two categories: normal fluctuations – those caused by random, inevitable factors, and the data related to normal fluctuations follow a normal distribution. Abnormal fluctuations: These are variations in quality data caused by systematic factors. The values of the variance, as well as its positive or negative sign, often remain constant or change according to certain patterns; they have a definite direction, resulting in large differences between the values.
For products, no two products can be exactly the same; the differences in their quality characteristic values represent the variability in quality. There are many factors that cause fluctuations in product quality. From a statistical perspective, these factors can be divided into two main categories: systematic factors and random factors.

The difference in quality characteristics among products is nothing but variability in quality
The substance itself may experience fluctuations in mass as a result of certain external stimuli
