I am having a hard time trying to figure out a typo in a dataset exercise that I can not seem to find the right data value.
The exercise follows:
Note that you will have to use some detective skills for two of the data points. For the typo, what is the most likely typo that would result in a height of .90? For the missing data, we actually cannot know what the value should be. One best guess is to take the mean of the other Pin Oaks.
I was able to figure out the rest of the typos and the missing data but I am stuck on trying to find the typo that would result for the height of .90, I tried inputting 0.90 but that did not seem to be correct. Would someone mind explaining what I’m missing here?
Hey, I put in 9.0 and it worked, I think you have to look at the other values and see a similar range (i.e. they are all near 6-12, so 9 is a reasonable guess)
Hey, this makes sense. Is it just saying to use logic in this case ? Would this apply to working with a larger batch of data ?
