The median of \( : a+2, a, a-2, a-1, a+1 \) is

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

Bir regresyon modelinde elde edilen \( b=0.5, a=2 \) değerleri için regresyon denklemi nedir? a. \( Y=0.5 \mathrm{X}+2 \) b. Hiçbiri c. \( Y=2+0.5 \mathrm{X} \) d. \( Y=2+0.5 \) e. \( Y=0.5+2 \mathrm{X} \)

is lying between 2.11 and 2.20 Which display makes it easier to see the lower quartile? (dot plot, box plot, bar graph, histogram)

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

The outlier of the following values \( 32,37,36,5,40,38 \) and 39
