Sagot :

To find the measures of central tendency; first we rearrange the data as follows:

2061 - 2213 - 2315 - 2551 - 2765 - 2865 - 2973 - 3065 - 3285 - 4363

• Mean:

[tex]\begin{gathered} Mean=\frac{Sum\text{ }of\text{ }all\text{ }data}{Number\text{ }of\text{ }data} \\ \\ Mean=\frac{28456}{10} \end{gathered}[/tex]

Mean = 2845.6

Median:

[tex]\begin{gathered} Median=\frac{2765+2865}{2} \\ \\ Median=\frac{5630}{2} \end{gathered}[/tex]

Median = 2815

• Mode: None of the data is repeated. If no number is repeated within the data set, we say that ,the mode does not exist.

• Midrange:

[tex]\begin{gathered} Midrange=\frac{Highest\text{ }value+Lowest\text{ }value}{2} \\ \\ Midrange=\frac{4363+2061}{2} \\ \\ Midrange=\frac{6424}{2} \end{gathered}[/tex]

Midrange = 3212
