Explanation:
Replace Data Source
Replace Data Source is a feature that allows you to replace one data source with another one that has the same or similar fields and structure. It updates all the worksheets that use the original data source with the new one, without reloading the data. In this case, you want to replace the data source that contains order data from 2019 with the one that contains order data from 2020.
To replace the data source, you need to do the following steps:
* Go to the Data Source tab at the bottom of the workbook to see the data source page. You will see a table that shows the fields and values from the original data source.
* Click on the drop-down arrow next to the data source name at the top of the page and select Replace Data Source from the menu. This will open a dialog box that allows you to replace your data source with another one.
* Select the data source that contains order data from 2020 from the list of available data sources and click OK. This will replace your original data source with the new one and update your worksheet accordingly. You may need to fix any broken fields or calculations that result from the replacement.

質問 # 126
You have the following visualization.
You Create a table calculation named Rank_Score that has a formula of RANK(AVG([Score]), and you drag Rank_Score to Text on the Marks cards.
What is the Rank Score value for Student ID 4220?
A. 0
B. 1
C. 2
D. 3
正解：B
解説：
To determine the Rank Score value for Student ID 4220, we look at the visualization provided and apply the table calculation of RANK(AVG([Score])). This function will rank the average scores in ascending order by default, with the lowest score receiving the rank of 1.
Based on the provided visualization, the scores for the students are as follows (from lowest to highest average score):
* Student ID 4183: 39 (Rank 1)
* Student ID 4220: 71 (Rank 6)
* Student ID 4247: 71 (Rank 6, same score as ID 4220 so they share the same rank)
* Student ID 4124: 75.5
* Student ID 4050: 64
* Student ID 4205: 67
* Student ID 4056: 66
Since Student ID 4220 has an average score of 71, which is the third-highest score, it shares the rank with Student ID 4247. However, since Tableau ranks without gaps, the actual rank assigned is 6, considering that there are two students with a rank of 4 (due to the same average score being the second lowest), making the next rank number 6.
Note: The actual ranks for the highest scores are not provided, but they are not needed to determine the rank for Student ID 4220. https://help.tableau.com/current/prep/en-us/prep_calculations.htm
