What is “sameness”?

Sameness is a mathematical concept created as a way of comparing both changes in mean and standard deviation from one population of data to another.

yieldHUb’s own research into the mathematics behind sameness found that the formula provided would only detect increases in std deviation and mean. By adjusting the formula to create a symmetric sameness function, sameness in yieldHUB provides a single number that can be compared across tests using different values, ranges and units of data and will show shifts in mean and standard deviation.

This basically means the value of standard deviation is calculated and the comparison is always done with the wider distribution as the reference and the smaller as the comparison. The resulting sameness function is shown in figure 1.
