Dependent Sample t-Test: Sample Size Calculation Results - Quick Tab

Calculating Required Sample Size

Select the Quick tab of the Dependent Sample t-Test: Sample Size Calculation Results dialog box to access options to interactively view the results of sample size calculations and generate plots of required sample size as a function of quantities that affect sample size in practice.  

X-Axis Graphing Parameters
The entries in the boxes under X-Axis Graphing Parameters establish the start value, end value, and number of steps on the X-axis for the graphs specified under Sample Size Charts.
Start Es
In the Start Es box, enter the starting value of Es to use in the N vs. Es sample size chart.
End Es
In the End Es box, enter the final value of Es to use in the N vs. Es sample size chart.
Start Alpha
In the Start Alpha box, enter the starting value of Alpha to use in the N vs. Alpha sample size chart.
End Alpha
In the End Alpha box, enter the final value of Alpha to use in the N vs. Alpha sample size chart.
Start Power
In the Start Power box, enter the starting value of the power goal used in the N vs. Power sample size chart.
End Power
In the End Power box, enter the final value of the power goal used in the N vs. Power sample size chart.
No. of Steps.
In the No. of Steps box, enter the number of steps, or intervals, to plot on the X-axis in the charts specified in the Sample Size Charts group box.
Sample Size Charts
Use the buttons under Sample Size Charts to produce charts of required N as a function of power goal, standardized effect size, or Type I error rate. Note that parameters given under X-Axis Graphing Parameters control the range of values plotted on the X-axis and the number of steps plotted.
