Further differencing is reccommended
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.12 p-value = 0.09 indicates that the data is stationary.
The Shapiro-Wilk test returned W = 0.95 with a p-value =0.12 indicating the data follows a normal distribution.
A skewness score of 0.03 indicates the data are fairly symmetrical.
Hartigan's dip test score of 0.08 with a p-value of 0.08 inidcates the data is unimodal
