- Median and mode are the two measure of central tendency do not affect the outliers. Select one: True Falsearrow_forwardWhat does the "box" of a box-and-whisker plot encompass? Outliers None of these Minimum and maximum Q1, Q2, Q3arrow_forward(b) Predict what will happen to the data distribution if outlier exists in the data.arrow_forward
- It is widely claimed that a histogram is skewed to the left when the median is greater than the mean and to the right when the median is less than the mean. But there are exceptions to this claim. Demonstrate this exception by creating a data set that has at least 15 samples and plot the histogram.arrow_forward1. The two plots have similar distrubutions. Are the distrubutions skewed left, approximtly symmetric, or skewed right? 2. Which is greater, the mean or the median, within each plot? Why does this make snese, gicen the type of distrubution you identified in the first part? 3. The population has drastically declined over recent years. Does the data show a difference in bee prefrence towards high quality hives versus how quality hives? Usse statistical evidennce to support your response.arrow_forwardTrue or false. If the IQR of a dataset is 0 then any observation smaller than Q1 is classified as an outlier using the 1.5(IQR) rule.arrow_forward
- What is a data set outlier? Why is it important to identify outliers in a data set?arrow_forwardFor the dataset below, do a complete box-and-line plot analysis. 3 15 18 19 23 23 26 27 28 29 50 Your work must include:Quartiles: Q1, Q2, Q3Interquartile range (IQR) Upper Limit Lower Limit Adjacent Values Outliers. If you have outliers,you must explain why they are outliers. Don’t forget to draw the box and line plotarrow_forwardWhat is the slope of the median median line for the dataset in this table?arrow_forward
- For a box plot, here are 4 values at the low end of a dataset and 4 values near the high end of a set of dataset: 18, 18, 18, 18 ... 23, 23, 25, 25, ... If the lower fence or boundary for outlier determination is 16 and the upper fence or boundary is 24, what value would you connect the whisker to on the high side of the "box?"arrow_forwardExercise 6. Below is a box plot of life expectancy in years for 142 countries in 2007. Life Expectancy (years) 80 70 60 50 40 (a) Using the box plot, estimate Q1, the median, Q3, and the IQR. Also, are there any potential outliers? (b) What characteristics of the distribution are apparent in the histogram, but not in the box plot? 2arrow_forwardDescribe the natures of the two distributions (uniform, normal, skewed left, skewed right), and identify possible outliers.arrow_forward
