The tables below show the data collected for a researcher attempted to investigate if
tensile strength of fiber reinforced concrete is higher than plain concrete .He prepared 100
samples each and conducted laboratory tests to gauge the tensile strength (refer to table).

For the data :
Plain Concrete
∑𝑥 417
Mean = 𝑛

Mode = 8.1
∑(𝑋−𝑋)2
Varience ,𝑆 2 = 𝑛−1
= 1.474
∑𝑥 1515.6
Mean = = = 15.156
𝑛 100
Mode = 25.7
∑(𝑋−𝑋)2
Varience ,𝑆 2 = 𝑛−1
= 16.04168
From the descriptive analysis above, it shows that the highest mean for the numbers of
Tensile Strength (MPa) is 15.156which is for Fiber Reinforced Concrete. Meanwhile, from the data, we
are also can conclude that fiber Reinforced Concrete that are the most using to gauge the tensile
strength.
