which best describes the data

Answer:
The answer to that depends on what exactly you want to describe
The data shown is a series of experiments carried out a number of times from the picture shown four times
Explanation:
Statistics are used to describe a data set. the most common
characteristics we want to describe about a set of data are its
central tendency I.e mean median and mode
For this given experiments carried out say we want to describe or find the mean. the mean from the data set given is 14.8
14.7+14.8+14.9+15.1=59.5/4
=14.8.
