Confidence Interval for Proportion p is the population proportion (of a certain characteristic) To find a C% confidence interval, we need to know the z-score of the central C% in a standard-normal distribution. Call this 'z' Our confidence interval is p±z*SE(p) p is the sample proportion SE(p)=√(p(1-p)/n ^ ^ ^ ^

The 68% confidence interval for this example is between 78 and 82. The 95% confidence interval for this example is between 76 and 84. The 99.7% confidence interval for this example is between 74 and 86. Therefore, the larger the confidence level, the larger the interval. There is a trade-off between the two.

Figure 1 shows the normal curve and its relationship to percentile ranks and several types of standard scores, including scaled scores with a mean of 10, standard scores with a mean of 100, and T scores with a mean of 50. As shown, the mean is the 50th percentile. This means that 50% of the normative sample obtained this score or lower.
