Multiply k percent by the total number of values, n. If you have 10 pieces of data or values in the data set, n would equal 10. The resulting number you get is called the index. The average IQ is, by definition, 100; scores above 100 indicate a higher-than-average IQ, and scores below 100 indicate a lower-than-average IQ. Theoretically, scores can range from any number below or above 100. In practice, however, they do not meaningfully go much below 50 or above 150. .On this graph the 95th percentile is shaded in: For the 90th percentile 90 percent of scores are lower, which is shaded in on the graph.How intelligent am I if my IQ is 95? - Quora. Something went wrong. Wait a moment and try again.To find the percentile of a specific value in a normal distribution, find the z-score first by using the formula. Z= (x-μ)/σ where μ is the mean and σ is the standard deviation of the data set. Then look up that z-score on a z-score table. The corresponding number in the z-score table is the percentage of data below your value.c. The 95 percentile is at Z = 1.64. So the IQ score is 100 + (1.64 *. 15) = 100 + 24.6 = 124.6.A good score on the CCAT depends on the job you apply for. However, as a rule of thumb, a score at the top 20% of candidates is considered a good score. On the CCAT, that score is around 31. A score of 42 will put you on the top scale for ANY job the CCAT tests for. For comparison, the average CCAT score is 24.It is known, for instance, that 99.74% of values lie within 3 standard deviations of the mean, and virtually everything is within 4 standard deviations of the mean. Example 5.4.3 5.4. 3. Suppose that the cholesterol levels are normally distributed with a mean of 160 (mg/dl) with a standard deviation of 40 (mg/dl).Approximately 95% of the population always lies between a z ...
