Will this help with my child's High School Statistics homework?

Yes. StudyPug covers every Rhode Island Standards Statistics topic, from data displays and distributions to probability rules and simulations, so students can get targeted help on whatever their class is working on.

How long are the video lessons?

Most video lessons run between a few minutes and about ten minutes, making them easy to fit into a homework session. Students can pause, rewind, and re-watch as many times as they need to understand the material.

Is there a state test for High School Statistics in Rhode Island?

Rhode Island administers the RICAS assessment, but it targets grades 3 through 8. High school end-of-course assessments vary by school and district, so check with your student's teacher about what assessments apply to their Statistics course.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your student can watch lessons and complete practice problems whether they are at home, at school, or on the go.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can see the content before committing. There is also a 30-day money-back guarantee, so your family can start with confidence.

CC.HSS.IC.B.4Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling.
- Margin of error
- Confidence intervals to estimate population mean
- Making a confidence interval
CC.HSS.IC.B.5Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant.
- Traditional hypothesis testing
- P-value hypothesis testing
- Analysis of variance (ANOVA)
CC.HSS.IC.B.6Evaluate reports based on data.
- Influencing factors in data collection
CC.HSS.CP.A.2Understand that two events A and B are independent if the probability of A and B occurring together is the product of their probabilities, and use this characterization to determine if they are independent.
- Probability of independent events
- Multiplication rule for
- Probability of independent events
CC.HSS.CP.A.3Understand the conditional probability of A given B as P(A and B)/P(B), and interpret independence of A and B as saying that the conditional probability of A given B is the same as the probability of A, and the conditional probability of B given A is the same as the probability of B.
- Conditional probability
CC.HSS.CP.A.5Recognize and explain the concepts of conditional probability and independence in everyday language and everyday situations.
- Comparing experimental and theoretical probability
CC.HSS.CP.B.7Apply the Addition Rule, P(A or B) = P(A) + P(B) - P(A and B), and interpret the answer in terms of the model.
- Addition rule for
CC.HSS.CP.B.9Use permutations and combinations to compute probabilities of compound events and solve problems.

How StudyPug Helps Rhode Island High School Statistics Students

When a student gets stuck on correlation versus causation or cannot work through a conditional probability problem, StudyPug gives them a clear video lesson to watch at their own pace, followed by practice problems with step-by-step solutions so they can check their reasoning and build confidence before the next class.

Students preparing for district or school-level Statistics assessments can use StudyPug to review specific strands - whether that means revisiting normal distribution estimates, practicing scatter plot interpretation, or working through expected value problems - without having to sit through material they already know.
