과제 내용

과제는 아래를 포함하는 내용이어야 합니다.

Factor B: Fullness
Factor A:
Weight
Empty Full
Normal n=20
$\overline{X}=22$
T=440
SS=1540
n=20
$\overline{X}$ =15
T=300
SS=1270
$T_\text{Normal}=740$
Obese n=20
$\overline{X}$ = 17
T=340
SS=1320
n=20
$\overline{X}$ = 18
T=360
SS=1266
$T_\text{obese} = 700$
$T_\text{empty} =780$ $T_\text{full} = 660$ G=1440
N=80
$\Sigma{X^2}=31836$

$\overline{X_{t}}= 18 $

$\overline{X_{t}}^2= 324 $

$N = 80 $

$N*(\overline{X_t}^2) = 25920 $

$\sum{X^2} - N*(\overline{X_t}^2) = 31836 - 25920 = 5916$

step 1. Build hypotheses
step 2. Locate the critical range for F-ratio. calculate the $dfs$

  1. $df_{total}$
  2. $df_{within}$
  3. $df_{between}$
    1. $df_A$
    2. $df_B$
    3. $df_{AxB}$

Compute F-ratio
SS

  1. $SS_{total}$

$\overline{X_{t}}= 18 $

$\overline{X_{t}}^2= 324 $

$N = 80 $

$N*(\overline{X_t}^2) = 25920 $

$\Sigma{X^2} - N*(\overline{X_t}^2) = 31836 - 25920 = 5916$

  1. $SS_{within}$

$SS_{within} = \Sum{SS_{within}} = 1540 + 1270 + 1320 + 1266 = 5396$

  1. $SS_{between}$
  1. $SS_A$
  2. $SS_B$
  3. $SS_{AxB}$

MS

  1. $MS_{A}$
  2. $MS_{B}$
  3. $MS_{AxB}$
  4. $MS_{Within}$

F-ratio

  1. $F_{A}$
  2. $F_{B}$
  3. $F_{AxB}$
