Hot Spot Analysis Zero Variance Error

I am running Optimized Hot Spot Analysis on data that shows a percent change between two years. I have multiple fields that I am running it on. However one of my fields keeps returning "ERROR 000906: Zero Variance: All of the values for your input are likely the same." However, the values in this field are not all the same, they range from -1 to 75, although 75 is an outlier and most of data is from -1 to 1. I thought maybe the negative and positive values were canceling each other out so I added 1 to each value so they were all positive but it still returned same result. Any idea why this is happening and is there a way to fix it? Thanks.
