Note
• You can use the setup screen “Background” setting to display the background image of the
Distribution mode graph screen. This is the same as the Graph mode. For details, see
“Displaying a Graph Background Image” (page 5-10).
• You can change the coordinate axes and label display on the graph screen using “Grid”,
“Axes”, and “Label” on the setup screen. This is the same as the Graph mode. For details,
see “Displaying and Hiding Graph Axes and Label on the Graph Screen” (page 5-18).
3. Other Operations
k Graph Screen Re-calculation and Inverse Calculation
Changing the x value on the graph screen re-calculates the probability value. Changing the
probability value performs inverse calculation of the x value.
Graph Screen Re-calculation
Changing the data value (x) or the Lower boundary (Lower) and Upper boundary (Upper)
causes the probability value ( p) to be re-calculated. To re-calculate, change the highlighted
value in the formula on the graph screen. See the sample screen below.
P (X ≤ x ) = p
P ( Lower ≤ X ≤ Upper ) = p
P (X ≥ x ) = p
P (X = x ) = p (discrete distribution only)
Note
• Re-calculation can be executed regardless of the distribution type and/or Tail setting.
Graph Screen Inverse Calculation
Changing the probability values ( p) causes the data value (x) to be inversely calculated. To
perform inverse calculation, change the highlighted value in the formula on the graph screen.
See the sample screen below.
P (X ≤ x) = p
P (Lower ≤ X ≤ Upper) = p (Normal distribution only)
P (X ≥
x) = p
