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
