Look at the images below (Activity 2 Data file Gliders) and answer these questions: 1. Trial 3 has the following numbers: 74.1, 75.7, and 1.6. Wr"te a sentence (or two) explaining what those represent in terms of glide distances. 2. Trial 5 has a negative number in its "difference" slot -- Wr"te a sentence explaining what that means happened in that particular trial. 3. Calculate the 5-number summary for the "differences" column of data. NOTE: in the data, you can have it automatically sort it into numerical order: select the differences data column by clicking on the first entry, the 8.9 and dragging down to the last data, the 8.7 - this creates a darkened box around that data. Then in the ribbon across the top, near the right side you'll see "Sort & Filter". Click that and choose the first option, the sort smallest to largest. A box will pop up and ask if you want to expand the selection - yes, you want that, so click the "sort" button. That will rearrange the trials into lowest to highest, making it much easier to get your 5-number summary. 4. State your IQR. Determine the lower and upper fence values and state them. Say if there are any outliers. 5. Suppose the author indicated that one of the trials was unusual. In this trial, one flight experienced an updraft of wind that caused an unusually long time to descend 800 ft, making the difference for this pair quite a bit larger than the other pairs. As such, it is reasonable to remove this trial from the data set because the condition of calm winds was not maintained. Which trial is this talking about? 6. Remove that line and then re-calculate your 5-number summary. Draw a box-plot of this data (by hand or with technology)
