How Do I Calculate Markup?

The statistical symbol is referred to as the symbol, which refers to the name of the common characteristics of each unit of the statistical population.

From a different perspective, each

1. According to the variation, it can be divided into invariant signs and mutation signs.

When the specific performance of a statistical mark in each unit is the same, this mark is called an invariant mark; when the specific performance of a mark in each unit may be different, this mark is called a variable mark or a mutation mark.

For example, China s Fifth Census stipulated that the object of the census is a person who has nationality of the People s Republic of China and is resident in the territory of the People s Republic of China. According to this provision, among the population as a survey object, nationality Domestic residence is a constant sign, while gender, age, nationality, occupation, etc. are variable signs. Invariant sign is constituted

Comparison of statistical signs and sign performance

A statistical mark is a name that describes the attributes and characteristics that a general unit has in common. The performance of the logo is the specific embodiment of the characteristics of the logo in each unit. If the mark is the item to be investigated by the statistics, the performance of the mark is the result of the survey and the actual reflection of the mark. For example: the gender of the employee is "female", the age is 32 years old, the ethnic group is the Han nationality, etc. Here, "female", "32 years old", and "Han nationality" are the specific manifestations of gender, age, and ethnicity, that is, the sign performance.

Mark performance is divided into quality mark performance and quantity mark performance. The performance of a quality mark can only be expressed in words, so it cannot be converted into a statistical indicator, but a statistical indicator is formed when the corresponding units are totaled. The number mark performance is a specific value, also called the mark value.

As far as a quality mark or quantity mark is concerned, its specific performance may be diverse, and the mark cannot be confused with the performance of the mark. For example, if you calculate the average of the monthly wages of three workers, you can only say that you calculate the average of the three flags or the value of three flags (variable values). That is, the worker's "monthly wage".

Differences between statistical signs and statistical indicators

I. Statistical indicators describe the characteristics of the overall unit, and statistical indicators describe the overall characteristics.

2. Statistical signs The quality signs represented by text and the quantitative signs represented by numbers. The statistical indicators are all represented by numerical values. There are no indicators that cannot be represented by numerical values.

The connection between statistical signs and statistical indicators

First, the numerical value of the statistical index is a result of the overall unit of the number of marks.

2. There is a transformation relationship between statistical indicators and statistical indicators. If the original statistical population becomes a total unit due to changes in the purpose of statistical research, the corresponding statistical indicators will also become quantitative indicators. Conversely, if the original total unit becomes a total, the corresponding quantity mark also becomes a statistical indicator.
