  1. Sign Test and Run Test Raymond L. Tremblay

  2. BioConservación • Biol 4037 • LWV 12:30-1:20

  3. Los temas • Regresión Lineal • Comparando ecuaciones lineales • Bondad de ajuste (Chi square) • Tabla de contingencia • The sign test (la prueba de signos) p 538 • The run test (la prueba de corrida) p 584

  4. La Hipotesis • Ho: There is no difference between hindleg and foreleg lenght in deer • Ha: There is a difference between hindleg and foreleg lenght in deer

  5. Tabla B.27 • El valor critico de C0.05(2),10 = 1 • n - C0.05(2),10 = 10 - 1 = 9 • - = 2 and + = 8. • Como 2 y 8 no son menor o mayor de 1 y 9 Ho es aceptado.

  6. Run Test • Serial Randomness or Nominal-Scale Categories • Dos differentes categories pueden aparecer de forma serial en espacio o tiempo.

  7. BAABBAAAAABBBBBAABAABAA • B = 10 • A = 13 • µ = 10

  8. Ho: La distribución serial de los miembros A y B son al azar • Ha: La distribución serial de los miembros A y B no son al azar

  9. µ0.05(2),10,13 = 7, 18 • Como 10 no son mas pequeño qué 7 o más grande qué 18 no se rechaza la Ho.

  10. Para n’s mayor de 30
