The number of deaths by suspected suicide ranged from 19 deaths in November 2022 to 36 deaths in September 2022 and March 2023. The mean (average) number of deaths was 30 per month and the standard deviation was 6. It is expected that around two thirds of the time that counts would be inside one standard deviation of the mean, and this was the case for 10 out of 12 months, so the variation seen is what would be expected.
From these data you cannot conclude that there was any significant variation in the number of deaths by suspected suicide month on month.
