Question

suppose you made 5 measures of your walking stride and got the following values: 0.76 m, 0.77 m, 0.78 m, 0.74 m, and 0.75 m what is the average length (in meters) of your walking stride?

Explanation:

Step1: Sum the values

To find the average, first we sum all the stride lengths. The values are \(0.76\) m, \(0.77\) m, \(0.78\) m, \(0.74\) m, and \(0.75\) m. So the sum \(S=0.76 + 0.77+0.78 + 0.74+0.75\). Calculating this: \(0.76+0.77 = 1.53\), \(1.53+0.78=2.31\), \(2.31 + 0.74 = 3.05\), \(3.05+0.75=3.8\)

Step2: Divide by the number of values

There are 5 measurements. The formula for the average (mean) \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), where \(n = 5\) and \(\sum_{i=1}^{n}x_{i}=3.8\). So \(\bar{x}=\frac{3.8}{5}\)

Step3: Calculate the result

\(\frac{3.8}{5}=0.76\)

Answer:

\(0.76\)
