Do Now (3 mins) PKB (Prior Knowledge Box) Topic: Scatterplots/ Correlation and Graphs Misconceptions Complete this side only. List anything that you know about the above topic.

STANDARDS 7SDAP 1.1: Know various forms of display for ________; use the forms to _______ a single set of data or to ________ two sets of data. 7SDAP 1.2: Represent two numerical __________ on a scatterplot and informally describe how the data points are distributed and any apparent ___________ that exists between the ____ variables (e.g., between time spent on homework and grade level).

OBJECTIVES Huskies will be able to _________ from different displays of data, including scatterplots by __________the relationship of two variables. Huskies will be able to ________ scatterplots by ___________ the data given. Students will show a mastery by earning a 3 out of 4 (proficiency) on the exit slip.

VOCABULARY Scatterplot- A graph that shows the relationship between two _________.

VOCABULARY (cont.) Positive Correlation- As one measurement (x) _________, the other measurement (y) __________.

VOCABULARY (cont.) Negative Correlation-As one measurement (x) _________, the other measurement (y) __________.

VOCABULARY (cont.) Zero Correlation-The two measurements (x and y) are _____ related to each other.

Example 1

Example 2 1/5 x 1/5 = 1/25

You Try! ½ x 1/6 = 1/12

Example 3 2/16 x 6/16 = 1/8 x 3/8 = 3/64

You Try 1/8

You Try! Given: Variable x is Grade Level. Variable y is hours of Homework Each Week. Task: Using the data below, construct a scatter-plot. Question: What is the relationship between these two variables? X 1 2 3 4 5 6 7 8 9 10 11 12 Y 14 15 12/20 x 11/19 = 132/380 = 33/95 (divide by 4 to reduce)
