These mathematical terms can be explained by use of the following results that show the length of time in seconds a group of children took to swim a length:

Mark	Susan	Rita	Rebecca	Hannah	Robert	Matthew
9	11	9	15	12	9	10

The mode is the value that appears most often in a set of data. In this case, the mode is 9 seconds.

The mean is the total of all the values, divided by the number of values. To find the mean, we add up all the results and then divide them by the number of swimmers:

9 + 11 + 9 + 15 + 12 + 9 + 10 = 75

75 ÷ 7 = 10.71428.... which can be rounded up to 11

The median is the middle number in a list of numbers ordered from smallest to largest.

9, 9, 9, 10, 11, 12, 15

so 10 is the median of this set of results.

The range is the difference between the lowest value and the highest value, so the range here is 15 - 9 = 6.

Applying Heron's formula \begin{lgathered}s=\dfrac{a+b+c}{2} \\\\\text{ Area of }\triangle =\sqrt{s(s-a)(s-b)(s-c)}\end{lgathered}s=2a+b+c Area of △=√s(s−a)(s−b)(s−c) Therefore s=\dfrac{33+44+55}{2} = 66s=233+44+55=66 Now \begin{lgathered}\text{ Area of }\triangle =\sqrt{66(66-33)(66-44)(66-55)}= \sqrt{66\times 33\times 22\times 11} \\\\=\sqrt{11\times 2\times 3\times 11\times 3 \times 11\times 2\times 11} \\\\=11\times 11\times 2\times 3 = 726 m^{2}\end{lgathered} Area of △=66(66−33)(66−44)(66−55)=66×33×22×11=11×2×3×11×3×11×2×11=11×11×2×3=726m2 Cost of leveling the field 1m^{2}1m2 = Rs . 1.20 Cost of leveling the field 726m^{2}726m2 = Rs . 1.20x 726= Rs. 871.2 Hence, total cost of leveling the field is Rs. 871.2
