Question

For a school newspaper article, Cienna conducted a survey to find out students’ favorite subjects. She polled all the students in Mrs. Lopez’s advanced dance class. Why is her data likely to be skewed?
Honors dance students are more likely to enjoy dance than students in the general population, so dance may be overrepresented.

Cienna should have interviewed all the students in the school to get more accurate data.

Honors dance students are more likely to enjoy dance than students in the general population, so dance will be underrepresented.

Answer 2

As dance students are more likely to enjoy dance than any other subject Ciena's data will be likely to be skewed.

• For carrying out data analysis it is very important that the data collected should be from varied sources.
• If the data is not from varied sources it is possible that the data can be skewed, in simple terms, be similar.
• The survey conducted was for finding out the favorite subject of the students for a newspaper article.
• So the student should have asked the students from various groups and subjects instead this data was collected from the students of  Mrs. Lopez’s advanced dance class.
• Only the students whose favorite subject is dance will reach up to the level of advanced dance class and if they are going to be asked which is their favorite subject they will definitely choose dance.
• So, due to the above reason, Ciena's data will be likely to be skewed.
