To avoid bias, a blinded study may be of familial or hereditary essential tremors.

If a one-sided test is used buy zocor 10mg fast delivery, the direc- tion should be specified in the study design prior to data collection 20mg zocor amex. However, it is most unusual for researchers to be certain about the direction of effect before the study is conducted and, if they were, the study would probably not need to be conducted at all. Effect sizes can be used to describe the magnitude of the difference between two groups in either experimental or observational study designs. The standard deviation around each group’s mean value indicates the spread of the measurements in each group and is therefore a useful unit for describing the distance between the two mean values. The advantage of using an effect size to describe the difference between study groups is that unlike 95% confidence intervals and P values, the effect size is not related to the sample size. Effect sizes also allow comparisons across multiple outcome measures regardless of whether different measurements or scales have been used or whether there is variability between the samples. The pooled standard deviation is the root mean square of the two standard deviations and 56 Chapter 3 Mean 1 Mean 2 –4 –3 –2 – Standard deviations Figure 3. Cohen’s d should only be used when the data are normally distributed and this statistic is most accurate when the group sizes and the group standard deviations are equal. For example, effect sizes for educational research may be much smaller than that observed in medical or clinical research. A typical effect size of classroom-based educational interventions identified from a synthesis of over 300 meta-analyses on student achievement is 0. Therefore, when the sample size is not large, an adjusted d value called Hedges’s g is computed. This gives a slightly smaller, less biased estimate of the population effect size than is provided by Cohen’s d. If the sample size of the control group is large, the standard deviation will be an unbiased estimate of the population who have not received the new treatment or intervention.

The vast majority of authors agree that surgery for bilateral He or she will be able to hear stereo music, tell the direction of atresia of the external meatus should not be carried out before the age of five-to-six years and they point out that surgical treatment of younger patients is justified only if complications such as cholesteatoma are present. By this time, accurate audio- metric tests can be obtained, pneumatisation of the temporal bone is well advanced, and the children are capable of cooper- ating with postoperative care. Although most surgeons are comfortable operating on the first ear of a child with bilateral atresia as he or she approaches school age, some are reluctant to recommend surgery at that age in unilateral cases. Delay until adulthood, when the patient can make his or her own decision, is then recommended. Timing of microtia repair According to Jahrsdoerfer (2), what really matters is the coop- eration and dialogue between plastic and otological surgeons, and the willingness to integrate their ideas and surgical needs for the good of the patient. Bellucci (19) and Marquet (28) believed that atresia repair should precede microtia repair. It was their belief that the open- ing in the mastoid could only be made precisely when the orig- inal position of the auricular remnant and the Figure 17.
