While working on the data table today, I came across an item related to the temperature coefficient α of thermistors. I’m not quite sure what this coefficient means; could anyone please explain it to me?

Could your question be made a bit clearer?

The rate of change of the resistance value for every 1°C change in temperature is called the temperature coefficient of resistance. It is a physical quantity that indicates how the resistivity, which represents resistance, changes with temperature. Its value is equal to the ratio of the increase in resistivity per 1°C rise in temperature to the original resistivity; it is usually denoted by the letter α, and its unit is 1/°C, that is: α = ΔR ÷ R ÷ ΔT
