Chapter 12 Estimation
Estimation The inferential process of using sample statistics to estimate population
parameters. The goal of estimation is to use the sample data to obtain an estimate of the
unknown population mean. Estimation will determine how muc

Chapter 11 The t Test for Two Related Samples
Repeated-Measures Design or a Within-subject Design, is one in which a single sample of
individuals is measured more than once on the same dependent variable. The same subjects
are used in all of the treatment

Chapter 14 Repeated-Measures Analysis of Variance
(ANOVA)
Individual Differences refers to participant characteristics such as age, personality, and
gender that vary from one person to another and may influence the measurements that you
obtain for each pe

Chapter 10 The t Test for Two Independent Samples
Research Design a research design that uses a separate sample for each treatment
condition (or for each population) is called an Independent-Measures research design or a
Between-Subjects design. Example,

Chapter 7 Probability and Samples: The Distribution
of Sample Means
Distribution of Sampling Mean - is the collection of sample means for all the possible random
samples of a particular size (n) that can be obtained from a population. It describes the ent

Chapter 5 Introduction to Z-Scores
Raw Score original, unchanged scores that are the direct result of measurement (pg 139)
Z-Score specifies the precise location of each X value within a distribution. The sign of the zscore (+ or -) signifies whether the

Chapter 6 Probability
Binomial distribution - The distribution of probabilities, for each possible outcome, for a series
of observations of a dichotomous variable (pg )
Normal distribution - A symmetrical, bell-shaped distribution with proportions corresp

Chapter 4 - Variablity
Variability - to say things are variable means they are not all the same. variablitity provides a
quantitative measure of degree to which scores in a distribution are spread out or clustered
together. (pg 105)
Range - the distance b

Chapter 9 Introduction to the t Statistic
Estimated Standard Error (SM) is used as a estimate of the real standard error M when
the value of is unknown. It is computed from the sample variance or sample standard
deviation and provides an estimate of the s

Chapter 8 Introduction to Hypothesis Testing
Hypothesis Test is a statistical method that uses sample data to evaluate a hypothesis about
a population. It is a procedure that researchers use to draw inferences about the population of
interest. (pg 230)
