Dear student

5,6,4,6,8,4,2,8,6,51) Mean=Sum of numbersTotal numbers=5+6+4+6+8+4+2+8+6+510=5410=5.42)Median2,4,4,5,5,6,6,6,8,8Median=5+62=112=5.53) Mode:The mode of a set of data values is the value that appears most often.So, here mode=6 64)Range =Highest value-lowest value=8-6=25) Standard deviation :Mean=5.4Variance σ2=xi-x2n=0.42+0.62+1.42+0.62+2.62+1.42+3.42+2.62+0.62+0.4210=0.16+0.36+1.96+0.36+6.76+1.96+11.56+6.76+0.36+0.1610=30.410=3.04Standard deviation σ=σ2=3.04=1.743
