95 Confidence Interval 1.96 Standard Error
Contents |
distribution used in probability and statistics. 95% of the area under a normal curve lies within roughly 1.96 standard deviations of the mean, and due to the central limit theorem, this number is therefore used z score for 95 confidence interval in the construction of approximate 95% confidence intervals. Its ubiquity is due to the arbitrary z value for 99 confidence interval but common convention of using confidence intervals with 95% coverage rather than other coverages (such as 90% or 99%).[1][2][3][4] This convention seems z score for 80 confidence interval particularly common in medical statistics,[5][6][7] but is also common in other areas of application, such as earth sciences,[8] social sciences and business research.[9] There is no single accepted name for this number; it is also commonly 95 confidence interval formula excel referred to as the "standard normal deviate", "normal score" or "Z score" for the 97.5 percentile point, or .975 point. If X has a standard normal distribution, i.e. X ~ N(0,1), P ( X > 1.96 ) = 0.025 , {\displaystyle \mathrm {P} (X>1.96)=0.025,\,} P ( X < 1.96 ) = 0.975 , {\displaystyle \mathrm {P} (X<1.96)=0.975,\,} and as the normal distribution is symmetric, P ( − 1.96 < X < 1.96 )
