and 360° as applied to twodimensional shapes on a coordinate

(D) model the effect on linear and area measurements
of dilated twodimensional shapes.
(11) Measurement and data. The student applies mathematical
process standards to use statistical procedures to describe data.
The student is expected to:
(A) construct a scatterplot and describe the observed
data to address questions of association such as linear, nonlinear,
and no association between bivariate data;
(B) determine the mean absolute deviation and use this
quantity as a measure of the average distance data are from the mean
using a data set of no more than 10 data points; and
(C) simulate generating random samples of the same
size from a population with known characteristics to develop the notion
of a random sample being representative of the population from which
it was selected.
(12) Personal financial literacy. The student applies
mathematical process standards to develop an economic way of thinking
and problem solving useful in one's life as a knowledgeable consumer
and investor. The student is expected to:
(A) solve realworld problems comparing how interest
rate and loan length affect the cost of credit;
(B) calculate the total cost of repaying a loan, including
credit cards and easy access loans, under various rates of interest
and over different periods using an online calculator;
(C) explain how small amounts of money invested regularly,
including money saved for college and retirement, grow over time;
(D) calculate and compare simple interest and compound
interest earnings;
(E) identify and explain the advantages and disadvantages
of different payment methods;
(F) analyze situations to determine if they represent
financially responsible decisions and identify the benefits of financial
responsibility and the costs of financial irresponsibility; and
(G) estimate the cost of a twoyear and fouryear college
education, including family contribution, and devise a periodic savings
plan for accumulating the money needed to contribute to the total
cost of attendance for at least the first year of college.
