What else can I help you with?
When comparing data between two different groupswhat do you do?
You make comparisons between their mean or median, their spread - as measured bu the inter-quartile range or standard deviation, their skewness, the underlying distributions.
How do you work out the range of values a box will extend in a boxplot using the mean score 100 and standard deviation 20?
It is not possible to determine the range since there is always the possibility that there are outliers. Also, there is no information about the skewness of the data. If the distribution is symmetric, there is a high probability (99.75%) that the values will lie within 3 standard deviations of the mean - that is between 40 and 160.
Would you consider two data sets similar or different if they have the same mean median and range but one is positively skewed and other negatively skewed?
If the skewness is different, then the data sets are different.Incidentally, there is one [largely obsolete] definition of skewness which is in terms of the mean and median. Under that definition, it would be impossible for two data sets to have equal means and equal medians but opposite skewness.
What 6 numbers have a mean of 4 and a range of 2?
{3,4,4,4,4,5} or {3,3,3,5,5,5} or {3,3.1,3.2,4.8,4.9,5}. These are some examples of symmetric sets.
What is geographic Distributions?
Geographic distributions refer to the patterns of where a species is found in a geographical area. It provides insight into the range, abundance, and habitat preferences of a species. Geographic distributions can be influenced by factors such as climate, habitat availability, and interactions with other species.
Which value is NOT always a number in the data set it represents?
The range, median, mean, variance, standard deviation, absolute deviation, skewness, kurtosis, percentiles, quartiles, inter-quartile range - take your pick. It would have been simpler to ask which value IS in the data set!
How do you solve ungrouped data?
You cannot "solve" ungrouped data since ungrouped data is not a question. You can calculate the mean or the variance, standard deviation or skewness, or a whole range of other measures for ungrouped data. But you have not specified what.
Is median used for when there is a wide range of numbers?
If the wide range is evenly spread between the very small and the very large (the distribution is symmetric) then there is not much to choose between the median and the mean. If not, the median will have some advantages as a measure of central tendency.
What is the population of the cascade range?
its approximately about 2 people;)
What is the normal T4 range?
Approximately 4.5 to 12.5
What has the author J L Howland written?
J. L. Howland has written: 'Report on digital analysis of ballistics range data, Case IV' 'The analysis of aeroballistic range data by the method of differential corrections for symmetric rounds with constant roll rate'
What kind of conclusions could you make about box and whisker plots?
It is a useful scheme to summarise data. It provides information on the central tendency (median) and a measure of spread (inter-quartile range). The total range is also indicated and outliers are separately identified. The location of the median within the IQR "box" provides an indication of the skewness of the data.
