Warnings

Scenario: sql/obfuscate_sql_string, Metric: execution_time

Sample size is 100, which is lower than 105.

The minimal sample size in case of normal distribution to achieve significance
level of 0.05 for difference of means with effect size Cohen's d = 0.5 must be at
least 105.

The conclusions from confidence intervals may be invalid.

Warnings

Scenario: sql/obfuscate_sql_string, Metric: execution_time

Measurements are autocorrelated.

Autocorrelation is present for lags 1..10.

The measurements are not independent, thus confidence intervals
may be less precise.
