Question: Anita made observations of the maximum temperature, t on 50 days. Her results are summarised by Σt=910 and Σ(t-ṫ)=876 where ṫ denotes the mean of the 50 observations. Calculate the standard deviation of the observations.
Edit
Answer: variance=1/n{Σ(t-ṫ)^2}=876^2/50=15347.52
standard deviation=sqrt(variance)=sqrt(15347.52)=123.88(Ans.) Edit
