1

What are key General Strategies for AP Statistics?

Be Specific: Use numerical values and context for clarity. Define and Show Work: Define variables and show calculations step-by-step. Read Carefully: Understand question requirements before answering. Check Your Answers: Review your solutions for errors.

2

What does the CUSS method stand for in descriptive statistics?

CUSS Method: Center, Unusual features, Spread, Shape.

New cards
3

What are the components of the SOCS method for analyzing data?

SOCS Method: Shape, Outliers, Center, Spread.

New cards
4

What are the steps in the DUFS method for describing scatterplots?

DUFS Method: Direction, Unusual features, Form, Strength.

New cards
5

What are the properties of a Binomial Distribution (BINS)?

B: Binary outcomes (success/failure), I: Independent trials, N: Fixed number of trials, S: Constant success probability.

New cards
6

What is the PANIC method for constructing confidence intervals?

PANIC: P (Parameter), A (Assumptions), N (Name the interval), I (Interval calculation), C (Conclusion).

New cards
7

What does the PHANTOMS method stand for in hypothesis testing?

PHANTOMS: P (Parameter), H (Hypotheses), A (Assumptions), N (Identify test), T (Test statistic), O (p-value), M (Decision), S (Conclusion in context).

New cards
8

What does the slope in regression analysis indicate?

Slope indicates how much y changes for each unit increase in x.

New cards
9

What does the Coefficient of Determination (R2) represent?

R2 indicates the percentage of variability in y explained by x.

New cards
10

What is a Type I Error in hypothesis testing?

Type I Error: Rejecting the null hypothesis (H0) when it is true.

New cards
11

What is a Type II Error in hypothesis testing?

Type II Error: Failing to reject the null hypothesis (H0) when the alternative hypothesis (Ha) is true.

New cards
12

What is the definition of Standard Deviation?

Standard Deviation (σ or s) measures the spread of data points around the mean.

New cards
13

What is the formula for calculating a Z-Score?

Z-Score is calculated as Z = (X - mean) / standard deviation.

New cards
14

What does Central Limit Theorem (CLT) state?

The Central Limit Theorem states that for large samples (n ≥ 30), the sampling distribution of the sample mean is approximately normally distributed.

New cards
15

What does the term 'outlier' refer to?

An outlier is a data point that markedly differs from the other observations in a dataset.

New cards
16

What does the term 'skewed right' indicate about data distribution?

A skewed right distribution has a longer tail on the right side, causing the mean to be greater than the median.

New cards
17

What does the term 'skewed left' indicate about data distribution?

A skewed left distribution has a longer tail on the left side, causing the mean to be less than the median.

New cards
18

What is the role of the mean in a symmetrical distribution?

In a symmetrical distribution, the mean is approximately equal to the median.

New cards
19

Define 'voluntary response bias.'

Voluntary response bias occurs when participants self-select into a survey or study, often leading to non-representative samples.

New cards
20

What are the main characteristics of a simple random sample (SRS)?

In a simple random sample, every individual in the population has an equal chance of being selected.

New cards
21

How do you determine the 'spread' of a dataset?

Spread can be measured using the range, interquartile range (IQR), or standard deviation.

New cards
22

What is the purpose of a boxplot?

A boxplot provides a visual summary of the data, showing the minimum, Q1, median, Q3, and maximum while identifying outliers.

New cards
23

How is a histogram used in statistics?

A histogram displays the frequency distribution of numerical data, helping to visualize the shape of the distribution.

New cards
24

What is the purpose of a scatterplot?

A scatterplot is used to visualize the relationship between two quantitative variables.

New cards
25

What does the term 'cumulative frequency' refer to?

Cumulative frequency is the total number of observations that fall below a particular value in a dataset.

New cards
26

What is the impact of increasing sample size on the power of a test?

Increasing sample size generally improves the power of a test, making it more likely to correctly reject a false null hypothesis.

New cards
27

What is a residual plot used for?

A residual plot is used to determine whether residuals exhibit any pattern, which may suggest the need for a different type of model.

New cards
28

What does 'strength' refer to when describing a relationship in regression?

Strength refers to how closely the points in a scatterplot follow a specific form, indicating the reliability of the association.

New cards
29

What are common types of graphs used to display categorical data?

Common graphs for categorical data include bar graphs, pie charts, and segmented bar graphs.

New cards
30

What is the notation for the population mean?

The population mean is denoted by the Greek letter mu (μ).

New cards
31

What is meant by 'normal distribution'?

A normal distribution is defined by its symmetrical bell shape, characterized by its mean and standard deviation.
