What is a scatter plot?

is the value that occurs most often. (median, mean, mode, outlier) \( =\frac{9}{2}-\frac{23}{6}=\frac{27}{6}-\frac{23}{6}=\frac{4}{6}=\frac{2}{3} \quad\left(\frac{5}{6}, \frac{1}{2}, \frac{1}{3},\left(\frac{2}{3}\right)\right. \)

\( \left. \begin{array} { c c c c c c } { x : } & { 10 } & { 15 } & { 20 } & { 25 } & { 30 } \\ { f : } & { 4 } & { 8 } & { 10 } & { 7 } & { 6 } \end{array} \right. \)

\( \left[\begin{array}{c|c|c|c|c|c|}\text { CI } & 10-20 & 20-30 & 30-40 & 40-50 & 50-60 \\ \hline \text { Nobt student } & 4 & 5 & 3 & 2 & 1\end{array}\right. \)
