The graph will contain error bars that represent the 95 % confidence interval. Graph Menu -> Interval Plot -> one Y-variable with groups -> Graph variable ( Enter the column containing the data), Categorical The codes used for the groups are appropriate for the graph (complete words).

(multiple Ys, simple) or in a single column with a corresponding code column (one Y, with groups).

****** Interval Plot: use this to visualize the relationship between several means. MEDIAN are the same, thus the middle 50% of the values are evenly distributed to either side of the MEAN. In a perfect Normal Distribution the MEAN and In which the middle 50% of the values of the sample are located. Thus Q1-Q3 (the interquartile range) defines the area The three quartilesДivide the data into four, essentially equal parts. Or lower quartile and the third or upper quartile. Highest value (highest resting pulse rate in the sample for C1 lowest resting pulse rate in the sample for C1). Useful measure of the variation in a sample, preferable to standard deviation in most cases. It is the standard deviation divided by the square root of N. Recall that for a normal distribution 68% of the data values fall between one standard deviationДЄbove and one standard deviation below the mean.Д®rror of the mean. To discard the most extreme values that may fall well outside of the range of the majority of values in the sample.Дeviation, the average deviation of the individual measurements from the mean - a measure of how spread out theДata are. Then the lowest 5% and the highest 5% of the valuesДЄre discarded the remaining 90% are averaged to give the trimmed mean. First the data are sorted - lowest to highest. Is, in fact, the middle value if N is an even #, then the median is half way between the two middle values. pulse rates) are above, 50% below the median. The average resting pulse rate if you specified C1). In the sample (the total # of students in the sample).

Will be linked to information on when to apply it, how to organize the data in Minitab, and how to interpret the With your instructor and use one of the slightly less sensitive, non-parametric statistical tests.ДЄ summary of the major tests used in Biology 109 is given below. If the data are not normally distributed you will need to consult Often an experiment is designed to determine the difference caused by an experimental variable.ДЇor most of the experiments you will be doing we will assume the data form a normal distribution (bell-shapedД¬urve) and parametric statistics can be used.

Determining the 95% confidence interval.

This way you will not conduct the experiment and then find out you did not collect data in an appropriate way toДЄlthough not considered statistical tests, the following procedures will be helpful as you begin the analysis When designing an experiment you should have an idea of how you will analyze the data after it is collected.
