2.? Determine the type of question: determining the type of question helps to better understand the question to be answered. For example, do you need to compare the relationship between different data, or do you need to calculate the percentage or average of specific data?
3.? Find key information: find key information related to the problem in the data. You can mark or circle this information for later review.
4.? Statistics: For a given number, basic mathematical operations such as addition, subtraction, multiplication and division can be used to calculate statistics such as percentage and average.
5.? Pay attention to the unit: when performing mathematical operations, you need to pay attention to whether the units are the same. If they are different, they need to be converted into the same units for comparison or calculation.
6.? Inference conclusion: Through the inference and analysis of data, draw a conclusion and provide supporting evidence. Pay attention to whether the conclusion is reasonable and consider other possibilities.
7.? Check the answer: after the answer is completed, carefully check whether the answer is correct and check the errors in the calculation process.
The above are some data analysis answering skills, I hope to help you.
