Hallux abducto valgus (call it HAV) is a deformation of the big toe that often requires surgery. Doctors used X-rays to measure the angle (in degrees) of deformity in 38 consecutive patients under the age of 21 who came to a medical center for surgery to correct HAV. The angle is a measure of the seriousness of the deformity. Here are the data. 29 23 15 31 15 28 25 17 28 35 21 18 38 22 49 25 16 23 26 31 27 16 23 26 28 21 29 25 22 39 27 22 31 11 16 22 21 26 what is the standard deviation?
Solution: The formula for calculating Standard deviation is given below:
Standard deviation
Where
is the angle if ith patient
is mean angle of 38 patients
is
number of patients
Now lets calculate the mean angle of 38 patients
Now lets find the Standard deviation of the given data:
Therefore standard deviation is

Introduce the program. 2. Generate ARRAYSIZE random integers in the range [LO = 10 .. HI = 29], storing them in consecutive elements of an array. ARRAYSIZE should be set to 200....
You are curious about whether you can enhance the ability to hear differences between nonnative speech sounds when people learn a new language. You test your novel language training procedure on a group of 32 pariticipants using a pretest/posttest design. The pretest and the posttest measure performance as the number of correct trials out of 100. The data are shown on the right. Does the new language training procedure improve the perception of nonnative speech sounds? Number of correct items...
