Question

https://s3.amazonaws.com/wmx-api-production/courses/50731/images/GID3283.gif The two charts show how female and male survey respondents answered a question about how often they ate a certain type of food. The survey specified that "infrequently" meant more often than "rarely" but less often than "occasionally." Select from the drop-down menus the options that create the statement that most accurately reflects the information provided. Slightly less than GRAPH_1_PLACEHOLDER respondents indicated that they ate the food at most GRAPH_2_PLACEHOLDER . https://gmatclub.com/forum/download/file.php?id=87099 ID: 700243 GMAT-Club-Forum-c9b4jef4.png

This is an amazing question that has at least 3 additional layers of complexity in it over and above what a typical Graphics Interpretation question entails.

Complexity # 1: 
The dataset presents a qualitative scale that needs to be visualized into a scale such that we can translate what “atmost rarely or infrequently or occasionally” means.

Complexity # 2:    
As you know a GI question has two blanks.  Some of these blanks are two independent statements.  And some have dependent blanks.  This question statement is of the latter category and hence is worded such that we need to process both the blanks together.  This interdependence increases the complexity of processing.

Complexity # 3: 
The pie chart needs to be read and interpreted properly so that we can extract the correct information as required to answer the question asked.

So, as you go through this video solution pay close attention to how “owning the dataset” approach will help you navigate through the complexities in this GI question.

The 0.2, 0.4 etc figures on the pie chart show the fraction of respondents corresponding to 20%, 40% etc.

So a bit less than 0.2 of the female respondents (say about 19%) said that they ate that food rarely (about 8%) or infrequently (about 11%) - approximately.
A bit less than 0.4 of the female respondents (say about 38%) said that they ate that food rarely (about 8%) or infrequently (about 11%) or occasionally (about 19%) - approximately.
and so on.

This is how you will read the graphs.

Slightly less than ____ respondents indicated that they ate the food at most ____.

When we say 'at most' we are including all the regions before it. So if I say "30% respondents said that they ate that food at most occasionally" it means that "30% respondents said that they ate that food rarely or infrequently or occasionally".

10% of male is the middle of rarely so more than 10% of males ate that food rarely. Hence this will not fit in the options.
A little less than 20% of females (about 19%) did say that they ate that food at most infrequently (i.e. rarely + infrequently). Hence this works.

ANSWER: 20% females, infrequently

Note that none of the other options work. 30% females is right in the "occasionally" section and 40% males are well into the "infrequently" section.

anish777 · Answer

Although I got this wrong, does "at most" includes "rarely and infrequently" both ? If that is the case, then 20% females and infrequently should be the answer. 
I did not notice the at most part and marked 30% male and rarely instead.

chetan2u · Answer

Yes, at most would include everything that is below it.
For example: If data gives you number of students and scores in groups of 10, viz 10-20, 20-30 and so on, at most 80 would include all groups under it till 70-80.

MihirBathia · Answer

I got the answer as slightly 'less than 40% female, occasionally', which does not really seem wrong either. Am I missing out on something?

jaky_nguyen · Answer

anish777  I think you marked correctly when choosing '30% male and rarely', take a look at the explanation of gmat ninja in the video I included above

I got the answer as slightly 'less than 20% female, occasionally', wHAT IS WRONG IN IT

samarpan.g28 · Answer

Hi  krispy289 , you picked 'less than 20% female', correct? Now see the below table which I created just eyeing the pie charts. Do you see that for slightly less than 20% of females, the column header is 'Infrequently'? If it were 'occasionally' in the women's category, the percentage would have fallen between 19 to 38 approx.

Hope this helps.

satish_sahoo · Answer

The wordings made this a little complex and difficult to comprehend. But, here is what my thought process was let's say the answer to the question about how often they ate a certain type of food was 0.2 this is actually, 20% chance of eating. So, it starts from 0 till 20.

Now, the Slightly less than part in question is where I searched for a line closer to the indicator/marker lines (0.2,0.4,0.6,0.8,1.0).This is where I saw the line slightly less than 0.2 of female pie chart. And the drop down box confirmed it. Selected.

Next - Infrequently actually includes foods infrequent and rare(coz it started from0). So, infrequent was the one which was at most from 0 to 0.2

Having said this, it still all remained a little ambiguous and took 3.5 mins.

Please correct me if my reasoning has flaws.

Official Answer:

The table below gives rough estimates from the charts that are sufficient for solving this problem. For example, in the chart for female respondents, the angular diameter of the sector for “rarely” is clearly less than the angular diameter of the sector for “infrequently”, and both sectors combined make up about 20% of all female respondents. Therefore, less than 10% of the female respondents responded with “rarely”, or equivalently, “at most rarely”.

Female 
 Male 
 
   at most rarely  
  less than 10%  
  about 30%  
 
   at most infrequently  
  slightly less than 20%  
  more than 40%  
 
   at most occasionally  
  more than 35%  
  more than 50%

RO1  
 Selections A and D can clearly be discarded by looking at the estimates in the male column of the table above, and selection C can clearly be discarded by looking at the estimates in the female column of the table above. 
  The correct answer is  20% of the female .

RO2  
 In the table above, only selection B (infrequently) is paired with “slightly less than 20%”.
 The correct answer is    infrequently   .

Sure. Weirdly enough it marks it as wrong without giving the correct answers. I did submit and confirm the answer, just to be clear.
