SURVEY. 120 seconds. Q. In the median formula, which cf value of this distribution should be used to compute the median? answer choices. 1. **Interquartile range** = Upper quartile – lower quartile = 39 – 13 = 26. **Range** = largest value – smallest value = 65 – 5 = 60. When evaluating the quartiles, always remember to first arrange the data in increasing order. How to compute the **interquartile range** for a set of data?. Example: "32" is split into "3" (stem) and "2" (leaf). More Examples: Stem "1" Leaf "5" means 15. Stem "1" Leaf "6" means 16. Stem "2" Leaf "1" means 21. etc. The "stem" values are listed down, and the "leaf" values go right (or left) from the stem values. The "stem" is used to group the scores and each "leaf" shows the individual scores within.

The **interquartile** **range** (IQR) is therefore 18 - 4 = 14. You will notice that the fact there is an outlier in this data (60) which has had no bearing on the calculation of the **interquartile** **range**. A frequency polygon is actually pretty easy to construct: First, you need to have the frequency distribution of the data, either in terms of the frequency of individual values, or in terms of classes. Second, you put the classes (or individual values) on the X-axis, and their frequencies on the Y-axis, and graph all the corresponding (X, Y) points. The **interquartile** **range** (IQR) is a measure of how spread out the data is. Do not confuse this with the **range** which will be dealt with separately. Notation. To find the **interquartile** **range** we must divide the data into quarters known as "quartiles". This is given the symbol Q. Q0 = Minimum Value. Q1 = Lower Quartile = 25%. Q2 = Median = 50%. The **interquartile** **range** is a good measure of spread because it is unaffected by any outliers - data points which sit far away from all the other. The **interquartile** **range** is a method of measuring the spread of the middle 50% of the values and is useful since it ignore the extreme values. The lower quartile is (n+1)/4 th value (n is the ....

Sketch a box plot for this data, marking any outliers. An outlier is an observation that falls either 1.5×interquartile **range** above the upper quartile or 1.5×interquartile **range** below the lower quartile. To find the **interquartile range** we subtract the lower quartile (Q_1) from the upper quartile (Q_3). So, reading from the box plot we get: \text{ **Interquartile range** } = Q_3 - Q_1 = 10 - 4 = 6. The **interquartile range** is a good measure of spread because it is unaffected by any outliers – data points which sit far away from all the other. From this point, you can use your probability tree diagram to draw several conclusions such as: · The probability of getting heads first and tails second is 0.5x0.5 = 0.25. · The probability of getting at least one tails from two consecutive flips is 0.25 + 0.25 + 0.25 = 0.75.

The heaviest calf will be in the ' 14 ' stem. There is only one calf in this stem and its leaf is 3, so the weight of the heaviest calf is 143 pounds. The lightest calf will be the calf with the lowest value in the ' 9 ' stem, so the weight of the lightest calf is 93 pounds. 6 Topics Clip Number R A G Conversion Length 692, 693, 694, 705, 706 Percentages Percentage of an amount 84, 85, 86 Percentage increase 88, 91, 92, 94, 97, 98. A long time ago (have a look over here if you have forgotten) we have learned that to find the area of a triangle, we multiply the base by the height and then divide that answer by two (or multiply by one half). An essential part of that formula is that the base and the height need to make a 90 degree (perpendicular) angle (for actually you are calculating the area of half a rectangle). Step 1: Find the total for the original number of players: 5\times12=60 5 × 12 = 60. Step 2: Find the total after once the mean has changed, so 4\times10=40 4 × 10 = 40. Step 3: Calculate the difference between these two totals as that difference has been caused by the person who left: 60-40=20 60 − 40 = 20. 4) For each set of data in question 2, calculate the **range** and the **interquartile** **range**. 5) A sample of leaves from tree B was found to have median length 7.3cm, with **interquartile** **range** 0.35cm.

Sort data set with n elements and select n/2-th element. If the index n/2 is not an integer, then use interpolation between the surrounding elements (in this case median does not belong to the input data set). For example, for n=10 elements, the median is equal to the 5th element. For n=50 elements, the median is equal to the 25th of the. An understanding of frequency tables is fundamental. Using frequency tables, we can generate charts and graphs to show data, and we can calculate statistics such as averages, quartiles, the **range**, and the **interquartile** **range**.
