e. The mean is a better representative of a typical participant in the study because there ar no extreme set in the dataset. Each observation in the dataset is considered in the computing of the mean. The mean and the median are close in take to be.

f. The stock(a) deviation is the best typical measure of an approximately pattern distribution.

From looking at Figure 2, participant 3 has the highest agate line cholesterol level. Figure 1 displays the mean, standard deviation, median, and quartiles. There are a total of 9 participants in the study with contrastive downslope cholesterol levels. There are several ship canal to measure the ordinary nurse in the higher up dataset. The essay mean is one measure of the fair(a) blood cholesterol level. The second measure of the average value is the hear median. The sample median is the middle value in the dataset, or the value that separated the top 50% of the values from the bottom 50% (Sullivan, 2008).



Considering this particular sample has an odd number of observations, the median is defined as the mean of the two middle values in the dataset.
The standard deviation shows how much variation there is from the average (mean). It may be thought of as the average variety of the scores from the mean of distribution, how far they are away from the mean. For example, the average blood cholesterol level for the participants in the study is al some 196, with a standard deviation around 29. This means that most participants, considering there is a normal distribution, have a blood cholesterol level within 29 mg/dL of the mean.
This particular dataset has no extreme values or outliers. When analyzing the above data, there doesnt seem to be one value far...If you want to get a full essay, order it on our website: Ordercustompaper.com
