Why do teachers make it so difficult

[@OfficialCreepersClan]

Honestly a video from 11 years ago and was 2:30 taught me better then a present teacher that had 90 minutes to teach me this

There is no universal agreement on how to find Q1 and Q3. Here is what the calculator does:
1. Use the computed median to divide the ordered data into two halves. Do not include the median into the halves. In our case the media is not a data point so this makes no difference.
2. The lower quartile value is the median of the lower half of the data which has 6 data points. The upper quartile value is the median of the upper half of the data which has 6 data points.

How do you enter data if it is in the form of ranges vs frequencies. Do I come up with a median within the range?

[@Triniboii4Lyf3]

Thank you so much my friend, you have helped me a lot. :)

[@coreyhunt6930]

Awsome videos!
My Q1 & Q3 were slightly different than yours (13,24). Does that mean my calculator's software needs to be updated or is that difference acceptible?
