# How do I interpret this standard deviation:

They gave me data on the percentages by weight of a sample of 48 syrups and with them I made a table of frequencies, they asked me the value of the standard deviation and they gave me: 2.60, now how do I interpret the value of this standard deviation? !

What the standard deviation tells you is how scattered your data is with respect to the average, (you do not say how much it was). What we know is that: `
` \$\$ \ begin {align} & \ mu = media \\ & \ sigma = detour \ standard \\ & \ to \\ & In \ (\ mu- \ sigma, \ mu + \ sigma) \ text {are 68.27% of your data} \\ & In \ (\ mu-2 \ sigma, \ mu + 2 \ sigma) \ text {are 95.44% of your data} \\ & In \ (\ mu-3 \ sigma, \ mu + 3 \ sigma) \ text {are 99.73% of your data} \\ & \ end {align} \$\$ `Salu2`
