$$Q1=\frac{67+69}{2}=\frac{136}2=68 $$ The upper quartile {eq}Q3 {/eq} is the median of the upper half $$77,80,87,91 $$ namely $$Q3=\frac{80+87}{2}=\frac{167}2=83.5 $$ Test your current knowledge Practice How to Calculate Quartiles...
A spreadsheet and the QUARTILE function is the quickest way to find the upper quartile. For example, the function "=QUARTILE(A1:A53,3)" returns the third (upper) quartile of your dataset. What Is the Interquartile Range of a Data Set? The interquartile range is the middle 50% of measur...
or you can use the upper quartile formula. If you have a small set of numbers (under about 20), by hand is usually the easiest option. However, the formula works for all sets of numbers, from very small to very large. You may also want to use the formula if you are uncomfortable ...
The box plot is an excellent tool to visually represent descriptive statistics of a given dataset. It can show the range, interquartile range, median, mode, outliers, and all quartiles. First, create some data to represent with a box plot: Python >>> np.random.seed(seed=0) >>> x ...
Answer to: How do you get the interquartile range? Provide a step-by-step solution. Consider a sample with data of 27, 25, 20, 15, 30, 34, 28,...
The following probability density function is given: f(x) = \frac{1}{9}x - \frac{1}{324}x^3 & , 0 \leq x is less than 6 0 & , otherwise. Find the upper quartile. The discrete random variable X has the following probability distribution. p(x) = \frac{2x}{39} & , x = ...
Click here to watch it on YouTube. A boxplot, also called a box and whisker plot, is a graph that shows the dispersion and central tendency of a dataset using a five number summary. The dispersion — a measure of how spread out a data set is — includes quartiles and the inter...

In Excel, Q1 and Q3 represent the first and third quartiles of your data set, respectively. Q1 is the median of the lower half of your data, meaning 25% of the data points are below it, and 75% are above. Q3 is the median of the upper half, where 75% of the data points lie ...
That is why "*apple*" matches "Orange, Apple", note also that the COUNTIF function is not taking into account upper and lower letters. There is one more wildcard character you can use which is the question mark. The question mark allows you to match any single character. =COUNTIF(C7:...
