Elementary Statistics:A Step By Step Approach
(10E), © 2018Bluman
Perfect for Introductory StatisticsFor students whose mathematical background is limited to algebra, this is the quintessential general statistics text (not intended for AP® Statistics). Elementary Statistics: A Step by Step Approach follows a non-theoretical approach without formal proofs, explaining concepts intuitively and supporting them with abundant examples.
Key Features:• The text ensures relevancy and deepens
conceptual understanding by offering real-life problems for students to solve with data projects, statistics today and critical thinking elements.
• ALEKS® 360 can be paired with Elementary Statistics: A Step by Step Approach to help students master the course content via an individualized learning experience tailored to students’ unique strengths and weaknesses.
ALEKS 360 is a complete course solution that combines personalized assessment and learning with a fully integrated, interactive eBook. The media-rich eBook features highlighting, bookmarking, and note-taking, while the dynamic ALEKS interface allows students to easily navigate their learning, track their progress, and manage their assignments from anywhere. Modern and mobile-ready, ALEKS 360 uses adaptive artificial intelligence to precisely identify what students know and don’t know in order to create individualized learning plans tailored to their unique needs.

STATISTICS TODAYStress and the College StudentA recent poll conducted by the mtvU/Associated Press found that
85% of college students reported that they experience stress daily.
The study said, “It is clear that being stressed is a fact of life on col-
lege campuses today.”
The study also reports that 74% of students’ stress comes from
school work, 71% from grades, and 62% from financial woes. The
report stated that 2240 undergraduate students were selected and
that the poll has a margin of error of ±3.0%.
In this chapter you will learn how to make a true estimate of a
parameter, what is meant by the margin of error, and whether or not
the sample size was large enough to represent all college students.
See Statistics Today—Revisited at the end of this chapter for
more details.
