Um die Werte in einem Streifendiagramm darstellen zu können, musst du zuerst die Prozentsätze berechnen. Du berechnest die Grundmenge G, indem du die Summer der Schüler berechnest:

Nun berechnest du die Prozentsätze der einzelnen Sportarten mit der Formel $\text{p}=\frac{\text{W}}{\text{G}}\backslash text\{p\}=\backslash frac\{\backslash text\{W\}\}\{\backslash text\{G\}\}$.

${\text{p}}_{\text{Fußball}}=\frac{\text{W}}{\text{G}}=\frac{9}{25}=\frac{36}{100}=36\mathrm{\%}\backslash text\{p\}\_\backslash text\{Fußball\}=\backslash frac\{\backslash text\{W\}\}\{\backslash text\{G\}\}=\backslash frac\{9\}\{25\}=\backslash frac\{36\}\{100\}=36\backslash \%$

${\text{p}}_{\text{Tanzen}}=\frac{\text{W}}{\text{G}}=\frac{3}{25}=\frac{12}{100}=12\mathrm{\%}\backslash text\{p\}\_\backslash text\{Tanzen\}=\backslash frac\{\backslash text\{W\}\}\{\backslash text\{G\}\}=\backslash frac\{3\}\{25\}=\backslash frac\{12\}\{100\}=12\backslash \%$

${\text{p}}_{\text{Handball}}=\frac{\text{W}}{\text{G}}=\frac{4}{25}=\frac{16}{100}=16\mathrm{\%}\backslash text\{p\}\_\backslash text\{Handball\}=\backslash frac\{\backslash text\{W\}\}\{\backslash text\{G\}\}=\backslash frac\{4\}\{25\}=\backslash frac\{16\}\{100\}=16\backslash \%$

${\text{p}}_{\text{Turnen}}=\frac{\text{W}}{\text{G}}=\frac{6}{25}=\frac{24}{100}=24\mathrm{\%}\backslash text\{p\}\_\backslash text\{Turnen\}=\backslash frac\{\backslash text\{W\}\}\{\backslash text\{G\}\}=\backslash frac\{6\}\{25\}=\backslash frac\{24\}\{100\}=24\backslash \%$

${\text{p}}_{\text{Sonstiges}}=\frac{\text{W}}{\text{G}}=\frac{3}{25}=\frac{12}{100}=12\mathrm{\%}\backslash text\{p\}\_\backslash text\{Sonstiges\}=\backslash frac\{\backslash text\{W\}\}\{\backslash text\{G\}\}=\backslash frac\{3\}\{25\}=\backslash frac\{12\}\{100\}=12\backslash \%$

Diese Werte kannst du nun in ein Streifendiagramm entragen:
