95% Confidence Interval for Mean Upper Bound – This is the upper (95%) confidence limit for the mean. f. 5% Trimmed Mean – This is the mean that would be obtained if the lower and upper 5% of values of the variable were deleted. If the value of the 5% trimmed mean is very different from the mean, this indicates that there are some outliers.

Trimmed Mean • The trimmed mean is produced by discarding the most extreme values – In SPSS, the trimmed mean is calculated by discarding the top and bottom 5% of the cases • The Trimmed Mean procedure is available through the Explore procedure • If the Trimmed Mean and Mean are similar it suggests that there are few, if any, influential Research design can be daunting for all types of researchers.

SPSS currently does not offer an option to plot trimmed means. You can plot them by capturing their values from the EXAMINE procedure (Analyze->Descriptive Statistics->Explore), where they are part of the default DESCRIPTIVES output, and plotting the captured values. The values for the trimmed means can be captured by using the OMS facility. I have a SPSS dataset in which I detected some significant outliers. The outliers were detected by boxplot and 5% trimmed mean. How do I deal with these outliers before doing linear regression?

You can plot them by capturing their values from the EXAMINE procedure (Analyze->Descriptive Statistics->Explore), where they are part of the default DESCRIPTIVES output, and plotting the captured values.

Levene's test works very simply: a larger variance means that -on average- the data values are “further away” from their mean. The figure below illustrates this: watch the histograms become “wider” as the variances increase.

He noticed that the mean, median, and trimmed mean are nearly identical.

V3 is V2 with 6 replaced by 100. This greatly affects the mean but the 2 middle values -and hence the median- stay the same. For example, Mean Substitution, Multiple Imputation and Expectation Maximization algorithm. Mean Substitution has a lot of critiques. In a way, it affect correlation between variables.

2011-07-01 · 5% Trimmed Mean is the mean after the highest and lowest 2.5% of the values have been removed. Skew-ness measures the degree and direction of asymmetry. A symmetric distribution such as a normal distribution has a skewness of 0, a distribution that is skewed to the left, when the mean is less than the median, has a negative
