An increasing number of journals echo this sentiment. This article will define confidence intervals CIsanswer common questions about using CIs, and offer tips for interpreting CIs. Asking the Right Question One of the many problems with null hypothesis significance testing NHST is that it encourages dichotomous thinking: Using a p value to merely test if there is a significant difference between groups does little to progress science.

Defining a CI A good way to think about a CI is as a range of plausible values for the population mean or another population parameter such as a correlationcalculated from our sample data see Figure 1.

A CI with a 95 percent confidence level has a 95 percent chance of capturing the population mean. Technically, this means that, if the experiment were repeated many times, 95 percent of the CIs would contain the true population mean.

CIs are ideally shown in the units of measurement used by the researcher, such as proportion of participants or milligrams of nicotine in a smoking cessation study. You can be reasonably sure that the population mean will What effect do the different levels somewhere in the range shown by the CI.

Think of precision as a measure of uncertainty associated with our estimate. An uncertain estimate using a 95 percent CI would be quite wide, whereas a more certain estimate using a 95 percent CI will be much smaller and therefore more precise.

The importance of replication in research has been increasingly emphasized, particularly in the social sciences Thompson, A CI provides the necessary information needed when conducting a meta-analysis and, most importantly, allows a researcher to immediately compare a current result with CIs from previous studies.

CIs can also be used to test hypotheses when necessary. You can easily estimate a p value from a CI; however, you cannot estimate a CI from a p value.

Essentially, CIs offer everything that p values offer and far more.

Wide CIs mean that there is not enough data or that the data are too variable to make a precise estimate. Proper planning can increase the likelihood of a precise interval. Much like an a priori power analysis, a researcher can estimate the number of participants required for a desired expected width.

The simplest method for planning the width of your CI is the precision approach, in which you place the standard deviation or an estimate if it is unknown and your desired margin of error the half width of your CI into the following equation: This margin of error will be your desired half width in the units in which you are measuring your dependant variable e.

This equation can replace the use of a power calculation to determine sample size. Common Misconceptions Definitional misconceptions.

Fidler found that some students believed a CI to be a range of plausible values for the sample mean, a range of individual scores, or a range of individual scores within one standard deviation. Remember, a CI is an estimate of plausible values for the population mean.

This, however, does not apply to repeated or paired design statistics. For repeated or paired designs, you should create a CI around the difference between the groups.

The confidence level misconception. Some believe that a 95 percent CI for an initial experiment has a 95 percent chance of capturing the sample mean for a repeat of the experiment.

This would only be true if the initial sample mean landed directly on the population mean. The CIs on the right are just touching.

Tips for Interpreting CIs Take note of what is most important to the study.Medium-level foods have a glycemic index of Eating many high-glycemic-index foods – which cause powerful spikes in blood sugar – can lead to an increased risk for type 2 diabetes, (2) heart disease, (3), (4) and overweight, (5, 6) (7).

Affect is a concept used in psychology to describe the experience of feeling or emotion. The term affect takes on a different meaning in other fields. Recent research suggests that high functional support is related to higher levels of positive affect.

Buffer systems built into most organisms prevent pH levels from reaching the point where essential enzymes are rendered ineffective. If an enzyme is rendered ineffective by pH level, adjusting the pH can cause the enzyme to become effective again.

‘The effect of different genres of music on the stress levels of kennelled dogs’ This may indicate an effect on the basal levels of cortisol secretion and HPA activity. Medium sized dogs were also found to have significantly higher UCCR than larger dogs. 5.

Conclusion. Beans, when germinating, prefer a pH level commensurate with what the mature plant best grows in, which is a range of to , placing it on the slightly acidic side of the scale.
