What is the first quartile of the data set below $275 257 301-218 265 242 201
To find the first quartile of a data set, you first need to order the data from least to greatest.
In this case, the ordered data set would be:
201 218 242 257 265 275 301
Since there are 7 data points, the first quartile would be the median of the lower half of the data set. In this case, the lower half is 201, 218, 242.
The median of the lower half is the middle value, which is 218.
Therefore, the first quartile of the data set is 218.
