Student Performance Statistical Analysis Skills

Data Set Division: Divide the data set into training set and test set for model training and evaluation. Exploratory data analysis (EDA) statistical description: By calculating the average score, highest score, lowest score and other statistical indicators of each subject, you can intuitively understand the overall situation of students' performance.

The complete process of statistical analysis of excel scores. We generally like to rank the students with the first place in the total score. As shown, we first find the total score of the subject. Enter the formula in the O2 cell =SUM (C2+E2+G2+I2+K2+M2), for example, complete the total score calculation of other students through the automatic filling function.

When using Excel to count scores, we usually sort them according to the high and low scores, and then automatically fill in the rankings in order. The randing obtained by this method is not related to the total score. Even if the score is the same, different scores will be filled in.

Use data analysis in excel to rank and percentage

1. Percentages are arranged in descending order , in order to get the real percentage ranking, a little adjustment is needed.

2. If order is not zero, Microsoft Excel ranks ref as an ascending data list. Count the score segment of each subject, as well as the pass rate, eugenic rate, comprehensive index, etc. Next, let's count the score segment of each subject, as well as the pass rate, eugenic rate, comprehensive index, etc.

3. Next, I will introduce some tips for using EXCEL to manage student performance.

4. First, open a spreadsheet, enter data in the table, and enter data in the spreadsheet. Select the sequence to display the percentage you want. Select the cell you need and right-click [Set Cell Format].

5. Enter 0 in the ranking method. After clicking OK, we can get the relevant rand. As shown in the figure below, with the same score, it shows its average and. Common functions Database functions When you need to analyze whether the values in the data list meet specific conditions, you can use the database worksheet function.

How to analyze the number of people and grades in each class?

Class Overview This semester, I coached the Chinese of Class 1 of Grade 4 and the head teacher of this class.The number of students in this class is 45. 43 people were actually tested. The average score is XX, the lowest score is XX, and the pass rate is XX.

Open the EXCEL table that needs to be operated, enter the function =COUNTIF ( in the target cell, and then click to select the cell area of the class. Continue to enter the number of classes that need to be counted in the function editing box, such as Class 1, and then enter to complete the input.

Create a new worksheet and enter the corresponding data in the form, such as subject, name, student number, student grades, etc. For example, we enter the grades of 24 students as a demonstration. The following data is the most primitive data collected by us, and we will process these data now.

that is, the number of students. Drag the formulas of cells B2 and C2 to the cells below to get the number of people passing and the pass rate of all subjects.Note: A2: A100 and B2 in the above formula need to be adjusted according to the actual situation to ensure that all students' performance data is covered.

So how to count the number of people in each score segment of Class 2? You only need to modify the formula of Class 1 "=COUNTIF (1! Z2: Z83, =590)" can be replaced with 2.
