		Proposed method		Reference method
Sample	𝑛	𝑥±𝑅[%]	𝑛	𝑥±𝑅[%]	𝑢	𝑢crit
Honey	4	33.84±5.63	4	33.97±2.16	0.017	0.406
Syrup	4	26.06±4.70	4	24.31±4.74	0.185	0.406

𝑛: number of measurements; 𝑥: arithmetic mean; 𝑅: range; 𝑢_crit and 𝑢: critical and calculated values of Lord’s test (selected probability—95%).
