Hi, I have a data set and I'm trying to re-create a summary table of statistics from a prior analysis. I'm able to re-create everything except for the t-test and wilcoxon p-value. When I try proc univariate or proc ttest, all the p-values I get are always <0.0001 no matter what variable I'm looking at. Any suggestions? Variable Birth Wt Nmiss Mean (std) Median IQR Range Nmiss Mean (std) Median IQR Range P_value P-value Birth Weight VLBW 0 1093.05 (284.4) 1140 846-1346 (525, 1500) 0 899.10 (277.24) 840 700-1159 (430, 1495) <.0001 <.0001 (gram) Non-VLBW 0 2830.32 (783.4) 2825 2160-3455 (1529, 4735) 0 2592.59 (764.4) 2410 1956-3118 (1505, 4224) 0.0343 0.0301 Head Circ VLBW 14 25.417 (2.561) 25.5 23-27.7 (20, 30.8) 9 24.203 (2.65) 24 22-26.3 (20, 30) 0.0068 0.0064 (cm) Non-VLBW 48 32.675 (2.675) 33 31-34.5 (23, 37.7) 12 31.83 (2.793) 32 30-34 (26, 42) 0.0559 0.0157
