Recently, one of my long-time friends and project co-administrators asked me a simple question. What do theFamilyTreeDNABig Y-700 testand the Time Tree tell us when we have genealogy trees provided by testers? What does the Discover Time Tree tell us that’s different, and how do we rec...
Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve. Sho...

The area under the curve is one. The curve never touches the x-axis. The curve is skewed to the right. 71. The cost of unleaded gasoline in the Bay Area once followed an unknown distribution with a mean of $4.59 and a standard deviation of $0.10. Sixteen gas stations from the Bay ...
IBM SPSS Exact Tests is easy to use. You can perform a test any time, with just a click of a button – during your original analysis or when you rerun it. With IBM SPSS Exact Tests, there is no steep learning curve, because you don’t need to...
2. By way of illustration, suppose that the point on the curve is (3, .013253) and sigma = 5. You can use Excel’s Solver to estimate the value of mu. This can be done by placing the formula =LOGNORM.DIST(3,A1,5,FALSE) in cell A2 and some initial guess for mu in cell A1...
The closer you get to zero, the flatter the curve gets. Can we ever flatten it out completely? Not for a continuous distribution with support over an infinite range. Why not? Because in order for the slope of [latex]value * density[/latex] to continue to flatline it indefinitely, the ...
Figure 2 – Equally spaced intervals Here, for example, cell Q18 contains the formula =SMALL($B$3:$I$22,40*(P18-1)+1), cell R18 contains the formula =SMALL($B$3:$I$22,40*P18) and cell S18 contains the formula =COUNTIFS($B$3:$I$22,”>=”&Q18,$B$3:$I$22,”<=”&...
