Vocabulary: ___________ is a graph of a set of data pairs (x, y)

What is SCATTER PLOT

Vocabulary: _______________ is a linear model used to fit a line to a data set

What is MEDIAN-MEDIAN LINE

For the scatter plot tell whether it has a positive, negative, or no correlation

What is POSITIVE CORRELATION

For the scatter plot tell whether it has a positive, negative, or no correlation

What is NO CORRELATION

Find the equation of the median- median line for the data below:

What is y = 2x + 36

Vocabulary: _________________ is the process of finding a the best fitting quadratic model for a set of data

What is QUADRATIC REGRESSION

Vocabulary: Finding a line or a curve that matches a set of data points is called _______________

What is CURVE FITTING

Write the quadratic function whose graph has vertex (-2, 3) and passes through the point (-1, 1)

What is y = -2(x + 2) + 3

Write the quadratic function whose graph has vertex (1, -4) and passes through the point (0, -3)

What is y = (x – 1) 2 - 4

Write a quadratic function whose graph has x-intercepts -2 and 1 and point (-1, -4)

What is y = 2(x + 2)(x – 1)

7.3/ Vocabulary: ____________ are numerical values used to summarize and compare sets of data

7.3/ What is STATISTICS

7.3/ Vocabulary: A normal distribution is modeled by a bell-shaped curve called a ________________ that is symmetric about the mean

7.3/ What is NORMAL CURVE

7.3/ Find the mean, median, and mode of the data set below

7.3/ What is Mean: 19, Median: 18, Mode: 17
