Hi Jin,
You can find the answer by trying to do in Tableau the action described.For ex. if you will drag the Customer ID field (using Superstore dataset), you will notice that a legend is also displayed that shows the color and value of each customer ID.
You can check the solution guide for more explanations – https://learningtableau.com/download/1472/. In the example mentioned there, the data is displayed at a month level first using a discrete date and after that as a continuous date.
In the first example, the data is aggregated at a monthly level without any difference of the year of each month – all sales made in February were summed even if they were made in 2011, 2012, or any other year.
In the second example, you can notice that the continuous date creates an axis that starts from the first individual date (in our example somewhere in November 2011 and ends in November 2015). While it’s presenting the data at a monthly level, it still shows the data differentiated by years.
Dimensions contain numeric, quantitative values whereas Measures can be used to categorize, segment, and reveal the details in the data
It seems to me it should be:
‘Measures’ contain numeric, quantitative values whereas ‘Dimensions’ can be used to categorize, segment, and reveal the details in the data.
Answer A is not the correct one because it is not complete, the complete answer is C which contains both the categorical palette and a legend with a color for each value of the field, while A mentioned only the categorical palette.
Option 2 is not correct because, although measures are usually continuous and dimensions discrete, this is not a difference between them. A measure can also be continuous and discrete, as well as a dimensions (dates for example).
Although the legend it is not mentioned in the link you’ve provided, I think that is happening because the legend is not in the scope of the article. I am using Tableau version 2023.1 and the legend appears on my worksheet.
What version are you using? Have you tried replicating the steps in the question?
Hi, option c is the correct one since it’s the options where it is specified that it displays the both the categorical palette and the legend.
Option a is about displaying only the categorical pallete. I know that the questions appear way to tricky but the real exam will have these kind of questions.
Hi Jin,

Hope this makes it clearer.

Hi,
For question No.5 why this choice is right? Would you mind giving any future explanation?
*Discrete date aggregates data at the selected unit whereas the Continuous date uses individual date values
Thanks！

It’s good explanation of the tricky answers for questions
Thanks Ramesh!
Hello,
for question 3, why c is correct?
Dimensions contain numeric, quantitative values whereas Measures can be used to categorize, segment, and reveal the details in the data
It seems to me it should be:
‘Measures’ contain numeric, quantitative values whereas ‘Dimensions’ can be used to categorize, segment, and reveal the details in the data.
Thank you for mentioning this mistake. It should be just A & E – C is incorrect. I made the correction.
Hello! For question No.4, Why A is not correct, since the explanation provided matches with A. Thank you for your explanation.
Hi Kristin,
Answer A is not the correct one because it is not complete, the complete answer is C which contains both the categorical palette and a legend with a color for each value of the field, while A mentioned only the categorical palette.
Hope this makes it clearer,

Hi,
Question 3: Measures contain continuous values with green pills whereas dimensions contain discrete values with blue pills. Why is it incorrect?
Thank you!
Hi Jim,
Option 2 is not correct because, although measures are usually continuous and dimensions discrete, this is not a difference between them. A measure can also be continuous and discrete, as well as a dimensions (dates for example).
Hope this makes it clear.
Thanks,
Narcis
The fourth answer is wrong. Please refer to the website
Hi Dovan,
Although the legend it is not mentioned in the link you’ve provided, I think that is happening because the legend is not in the scope of the article. I am using Tableau version 2023.1 and the legend appears on my worksheet.
What version are you using? Have you tried replicating the steps in the question?

Question 4 is incorrect, since it’s only talking about ‘Discrete field’ the correct option should be a)
Hi, option c is the correct one since it’s the options where it is specified that it displays the both the categorical palette and the legend.
Option a is about displaying only the categorical pallete. I know that the questions appear way to tricky but the real exam will have these kind of questions.
