Spring Board Course 1 6.SP.A.1 Lesson 27-1 Warm Up Page 346, #2 I. Objective II. Page 349 Go onto my website and click on the button labeled “survey” III. Statistical question – Variability – Distribution – IV. Answer the question. Determine if your answer would be the same as your classmates’. 1. How many cars are in the parking lot? 2. How many letters are in the word apple? 3. In what year will you graduate from college? Determine whether the question is a statistical question. 4. In what year was the Declaration of Independence signed? 5. How many pickles are in the pickle jar? 6. What night of the week do you watch your favorite show? V. Summarize Which of the questions for the survey has a lot of variability? Lesson 27-2 Warm Up Determine whether the question is a statistical question. Explain. 1. How long did you wait in line? 2. How many games did you bowl? 3. How many quarters are in a football game? I. Objective II. Categorical variables – Numerical variables – Mode – III. From Survey Students Eye Color Blue Brown Hazel Total Count Fraction Percent IV. A.K.A. – Bar graph Use to graph categorical data V. Summarize What is the mode of our eye color data? Lesson 27-2 Warm Up Use a number line to order the numbers from least to greatest. 1. 1.5, 4.5, 5, 2.5, 1, 3 2. 6, 3.5, 4, 5.5, 7.5, 4.5 I. Objective II. A.K.A. – line plot Used to graph numerical data Create a dot plot for the height of students in our class Draw a number line with scale Place a dot above the appropriate value III. Displays data that is organized by place value Create a stem-and-leaf Stem – tens digit Leaf – ones digit Needs a key Summary Can you identify the mode in either a dot plot or stem-n-leaf plot? Explain. Lesson 27-3 Warm Up Create a stem and leaf plot with the ages below. I. Objective II. Page 357, #1-2 III. Vocab Skewed – Symmetrical – Uniform – IV. Summarize Describes the distribution of the plot of our pets? https://learnzillion.com/lessons/3109-describe-the-shape-of-a-dot-plot https://learnzillion.com/lessons/537-analyze-the-shape-of-a-graph-to-describe-thedistribution-of-data Lesson 28-1 Warm Up Work with a partner. Discuss the distribution of the data. Where on the number line do you think the data set is balanced? Is this a good representation of the average? Explain. I. Objective II. Vocab Mean – or average – Ex: Find the mean of 3, 5, 7. Mean = ____ Outlier – III. Page 363, #1 IV. Summarize Explain how to calculate the mean. https://learnzillion.com/lessons/2482-find-the-mean-by-equally-distributing-objects https://learnzillion.com/lessons/534-find-the-mean-of-a-data-set Lesson 28-2 Warm Up Write a total number of letters in the first and last names of 9 celebrities, historical figures, or people you know. Organize your data in a table. I. Objective II. Order the values in your data set from least to greatest. Then write the data on a strip of grid paper with 9 boxes. Now take your strip of grid paper and fold it in half. On what number is the crease? What do you notice? This value is called the median. How many values are greater than the median? How many are less than the median? III. Median – IV. Page 369, #16 V. Summarize How would you describe to another student what the median of a data set represents? Lesson 28-3 Warm Up Page 370, #1-2 I. Objective II. Page 370, #3 III. Summarize Describe the difference between median and mean.
