For the data red, red, red, green, green, yellow, purple, black and blue, what can be reported?
ANo mode exists for words like these
BThe mode is red, since modes suit words
CThe mean is red, since red occurs most
DThe median is green, since it is central
Answer & Solution
Correct answer: B. The mode is red, since modes suit words
1. The mode is simply the most frequent category, so it does not need numbers.
2. Red appears three times, more than any other colour.
3. The mode is therefore red, and modes can be reported for qualitative data.
4. A mean cannot be formed from colours at all, since they cannot be added and divided.
