Next, let's look at other differences between the average and the average:
1. Different meanings: mean usually refers to the average in statistics, and average refers to the average of the total number divided by the number of observations.
Example:
-The average of the numbers 2, 4 and 6 is 4. ?
The average of two, four and six is four.
The average grade of the class is 75. ?
The average score of this class is 75.
2. Different application scenarios: mean is usually used for statistical analysis of continuous variables, while average can be applied to different types of variables.
Example:
-The average temperature this month is 25 degrees Celsius. ?
The average temperature this month is 25 degrees Celsius.
The average height of trees in the forest is 50 feet. ?
The average height of trees in the forest is 50 feet.
3. Different calculation methods: mean uses the sum of all measured values divided by the number of observations, while average can use various calculation methods, such as weighted average and median.
Example:
The average of -4, 7, 9 and 12 is (4+7+9+ 12)/4=8. ?
The average of the numbers 4, 7, 9 and 12 is (4+7+9+ 12)/4=8).
-Calculate the average score using a weighting system. ?
The average score of grades is calculated by a weighting system.
4. Different emphases: mean emphasizes the contribution of each measurement to the whole, while average emphasizes the influence of each observation.
Example:
The average weight of the group increased due to the addition of a large individual. ?
Adding a heavier individual will increase the average weight of the whole group.
The average salary of the company has been affected by the recent salary increase. ?
The recent salary increase has affected the average salary level of the company.
5. Different precision: the average value is more accurate, because it contains all the measured values, and the average value needs more information to calculate accurately.
Example:
The average score in the exam is 75.6. ?
The average score of this exam is 75.6.
-Without more data, it is difficult to determine the accurate average price of houses in this area. ?
