ind rive point summary for the data set (minimum, maximum, median, first quartile, thir aximum, median, first quartile, third quartile): Rearrange numbers in the data set Construct the lower part: What is the median of the lower part? How do we label it? What is the meaning of this median? What is the median of the upper part? Construct the upper part: How do we label it? What is the meaning of this median? Complete five points chart minimum first quartile median third quartile maximum Constructing: Use the five point summary to sketch the box and whisker plot for the data set above: Making conclusions: Based on box plot below, describe the data respond on the questions provided 12 15 18 + 1 1 + 14 + 16 + 18 + 20 + 22 24 26 28 + 30 + 32 34 + 36 + 38 + + 40 42 44 46 48 so What is the third quartile? Show it. A vertical line that goes through the box is the median. Here are the results: 13 It is hard to say what is the middle point say what is the middle point (the median) because the value points are not ordered. When we plot a graph for the box plot, we outline a box from the first quartile to the third quartile. What is the first step? State the answer: How can you so an vou solve the above problem missing number given the mean) numerically (non-algebraically?Īnalyzing data and preparing for box plot: Suppose you have the math test results for a class of 15 students. To achieve this, how many hits must he have on the sixth day? Define a variable: Let x represent Construct an algebraic expression for the sum Construct an algebraic expression for the mean (average) as a fraction Set up an equation (hint: what is the mean? Solve this equation below. In a box plot, we draw a box from the first quartile to the third quartile. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. He is hoping to have an average number of 70 hits per day in six days. A box and whisker plotalso called a box plotdisplays the five-number summary of a set of data. In the past five days, he has recorded the following number of daily hits: 52, 88, 52, 65, 35. Communication explain key statistics: Calculate the mean, median, mode and range for the 13, 24, 28, 25, 36, 28, 20 range for the following set of data (describe all steps) What if you include another number 20 to the data set? What happens with the key statistics? Real-life: Wendi's Candles sold the following number of candles over the last 7 days: 25, 18, 45, 45, 18, 50.25 What was the average number of candles sold each day? Missing data: William recently launched a new website. , mode, range and box plot L Topic: Mean, median, mode, range and bo Mathematics Competencies T M04.
