As the level of confidence decreases, the size of the corresponding interval will decrease. In most practical research, the standard deviation for the population of interest is not known. Whilst my eagerness to impress the interviewers is now embarrassingly obvious to me, I don’t think the statement is all that far from the truth. To say that P describes the probability that an observed effect is not a real one is mistaken.

Confidence intervals can be calculated for many different statistical quantities (proportions, difference between two means or two proportions, relative risks, odds ratios, et cetera), but the method of calculation varies.

What is the best Analysis method can be use to find out the Mean, Confidence interval and Standard error for the following agegroups? This entry was posted by Dave Higgins on Thursday, August 10th, 2006, at 12:01 pm, and was filed in All posts, Miscellaneous. For aerospace structures, the material strengths used in stress analysis are often based on the statistical variation of the materials. The confidence interval is used to describe how much faith we have in these reliability values.

The following illustrates what the 95% confidence means for a B-basis allowable based on a normal distribution. The figure shows the population true 10th percentile level at 1.28 standard deviations to the left of the mean. Mark has done a great job in writing complex statistical concepts in an easy to understand format that makes grasping them both easy to understand and to use. With the help of Mark's book, and some diligent studying, I received an A in my stats course. Excel Statistical Master that taught me all of the basic concepts for the different tests we used.

Unlike the indecipherable jargon in the countless books I have wasted money on, the language in this book is plain and easy to understand.

This same problem above is solved in the Excel Statistical Master with only 3 Excel formulas (and NO looking anything up on a Z Chart). This same problem above is solved in the Excel Statistical Master with only 3 Excel formulas (and not having to look anything up on a Z Chart).

This would state that the actual population Proportion has a 95%probability of lying within the calculated interval. The standard error of the mean is is the value we would expect if we took several samples, and computed all their means, and then took the standard deviation of those means. Eighty percent (80%) of the respondents agreed with the statement that social secirity benefits should not be taxed and 20% said they should be taxed. The larger your sample, the more likely the sample represents the population as a whole, and the more confident you can be about the mean.

Commonly used reliability values are 99% (referred to as A-basis allowables) and 90% reliability values (referred to as B-basis allowables). A confidence interval of 95% is specified in both MIL-HDBK-5 and MIL-HDBK-17 for calculating A and B basis values. We expect 90% (for a B-basis value) of the strength values from the population to be greater than this value, or falling on the right side of the 10th percentile line. I purchased the materials about halfway through the course and wish I had known about this manual from the start of the class! You'll be able to grasp your statistics course a LOT easier with the Excel Statistical Master.

If you found your statistics book confusing, You'll really like the Excel Statistical Master. So a P value, interpreted correctly, can tell us about the strength of evidence against the null hypothesis. This gives me (an undergraduate, BioStats student) enough information to understand the concept and enough explanation to practically apply. An illustration: If we sample the height of a billion people, the standard deviation will still be there (as it would if we measured absolutely everybody), but we would start being very confident about the average height of the human being. This means that only 1% and 10% of the material is likely to fall below these strength values. So for example, if you specify a mean value of a random sample of a population, a 95% CI of the mean indicates how confident we can be that the true population mean lies within the calculated confidence interval.

These data are communicated by a CI, and are important in determining the clinical significance of effects which we observe which we have decided are likely to be real ones. Additonally, by stating a CI, the P value can be roughly determined even if it is not explicitly stated.

If the P value is higher (above our arbitrary threshold of say, 0.05), the evidence against the null hypothesis is poor, and we fail to reject it. For example, if your 95% CI does not include zero (or if not zero, the value stated in the null hypothesis), then your P value will be less than 0.05.

Usually, the t look-up tables which are used correspond with two-tailed probability P (when the real value you want to estimate can go in either direction—up or down).
