How To Use Wiki In The Classroom
95% Confidence Interval, Image by author What is Bootstrap Method? Bootstrap Method is a resampling method that is commonly used in Data Science. It has been introduced by Bradley Efron in 1979. Mainly, it consists of the resampling our original sample with replacement (Bootstrap Sample) and generating Bootstrap replicates by using Summary Statistics. More and more classrooms are now learning, creating, reading, and testing online. In order to keep up with our technologically demanding lifestyles, the traditional classroom is making way for such innovative tools as wiki. Not only is this an inexpensive way to manage your classroom, it’s also a fun way to engage students in content across the curriculum.

Bootstrap confidence interval. Bootstrap confidence interval. December 8, 2020 postadmin Post in Uncategorized. The data file normal50.rda contains a random sample of size n = 50 for the situation described in Exercise 6.4.6. Download this data in. In addition to the BC interval, the percentile bootstrap interval and the bias-corrected with acceleration (BCa) bootstrap confidence interval are also popularly used in practice. When sample size is small to medium (e.g., less than 100), the aforementioned confidence intervals may have unsatisfactory performance with regards to coverage probability. Bootstrapping a confidence interval. A useful tool for assessing the variability of some data is the bootstrap. In this exercise, you'll write your own bootstrapping function that can be used to return a bootstrapped confidence interval. This function takes three parameters: a 2-D array of numbers ( data ), a list of percentiles to calculate.

A second option is to collapse over the observations in each discrete bin to plot an estimate of central tendency along with a confidence interval: sns Confidence interval using bootstrapping The first column contains the cultivar of a wine sample (labelled 1, 2 or 3), and the following thirteen columns contain the concentrations of the 13.

Basic Interval The CI are estimated by correcting the bootstrap distribution for bias, or skew, and solving for the estimates which capture 95% of the bootstrap statistics. seven sections provide a heuristic overview of four bootstrap confidence interval procedures: BCa, bootstrap-t, ABC and calibration. Sections 8 and 9 describe the theory behind these methods, and their close connec-tion with the likelihood-based confidence interval theory developed by Barndorff-Nielsen, Cox and Reid and others. Bootstrap estimate of the MSE. Moreover, we can estimate the MSE by MSE\(M n) = 1 B XB ‘=1 M (‘) M n 2: Bootstrap con dence interval. In addition, we can construct a 1 con dence interval of the population median via M n z 1 =2 q dVar B(M n): Well... this sounds a bit weird{we generate new data points by sampling from the existing data points.

The confidence interval with limits which are 2.5 and 97.5 percentiles of the bootstrap distribution, i.e., the limits of the central 95% of the bootstrap distribution. Point estimate. A single number that estimates the value of the parameter. For example, the value of a sample mean, x-, when estimating the value of a population mean u. Formula. To use the standard error, we replace the unknown parameter p with the statistic p̂. The result is the following formula for a confidence interval for a population proportion: p̂ +/- z* (p̂ (1 - p̂)/ n) 0.5 . Here the value of z* is determined by our level of confidence C.

In this video, I explain how to make a confidence interval with bootstrapping. Here, we go over how to make a confidence interval with the true population, h.

A confidence stated at a \(1-\alpha\) level can be thought of as the inverse of a significance level, \(\alpha\). One and two-sided confidence intervals: In the same way that statistical tests can be one or two-sided, confidence intervals can be one or two-sided. A two-sided confidence interval brackets the population parameter from above and.

  1. Set Clear Expectations
    Before setting wiki guidelines and sharing them with your students, consult your school’s policies on social media. Provide students with written guidelines that must be adhered to. Let students know that if they publish inappropriate content, there will be consequences. Asking students to sign a contract is also an option.
  2. Start Small
    Take baby steps. Everyone will benefit from gradually increasing wiki use in the classroom. By starting small, teacher’s can stay on top of monitoring classroom wiki, thus remaining in control.
  3. Ask for Help
    Although wiki is fairly easy to use, there are times when you’ll run into stumbling blocks. Ask for help when you don’t understand something. You’d be surprised at much your students and colleagues might know about wiki.
  4. Read other Wikis
    As a class and individually, explore other classroom wikis. This will give you ideas and inspirations for your own wiki pages.
  5. Let Wiki Work for You
    Wiki is more than just a learning tool for students; it’s a communication tool for teachers. Use wiki to keep parents informed and post assignments and other class related content. Your wiki page is easily edited and updated so there’s no more need for a last minute trip to the copy machine.
  6. School-wide Wikis
    Use wikis to showcase field trips, class events and school-wide events, such as the prom or last week’s football game.
  7. Pinterest
    This site has a wealth of information on wiki for the classroom. Simply type in a search term such as "wiki tips for the classroom".  If you don’t already have a Pinterest account, learn more about it through wal katha putha katha.
  8. Collaborate
    Do lots and lots of group work. Create assignments that require students to work together, continuously communicating as part of team as they would in the real world.  For example, a media class can work in teams to create an advertisement for a product of their choice that involves print and/or video.  For a science class, have students work together as a research team investigating the sudden drop in the local wolf population.

  1. Historical Figures
    Instead of just another boring academic paper on an historical figure, make research and documentation fun by creating wiki fan pages. Students can add and edit text, post photos and famous quotes, as well as links to the references they used.
  2. Student as Editor
    Turn grammar into a challenging and competitive game. Have students use wiki to edit text with grammatical errors. Teachers can put students into groups and those with the most edits wins.  Individual edits can also be counted.
  3. Join the Debate Team
    Using a written set of guidelines, teachers post topics that students can argue by using wiki online forums. Teachers will monitor the discussions/debates while students learn online debate etiquette.
  4. Create a Collaborative Story
    Start with one sentence pulled from a hat, “The girl looked beyond the dusty field and saw a team of horses approaching, their riders hands tied behind their backs.” From here, students add and edit text to create a story. Set a minimum amount of words each student must submit. Chances are, you’ll actually have to set a maximum amount of words.
  5. Poetry Class
    For English class, the teacher can post a poem online and have the students discuss its meaning.  Students can also post their own poems for peer review.
  6. Book and Film Reviews
    Students can use wiki to write assigned book and film reviews. Other students can add to as well as comment and discuss the reviews on a monitored forum.
  7. Word Problems
    For math class, teachers can post word problems on wiki. Students work individually or in groups to solve the problems.
  8. Wiki Worlds
    For history and social studies, students can create pages for historical events such as famous battles or specific periods in history, creating entire worlds based on historical facts.
  9. Geography
    Wiki pages can be used to study geography by giving states or countries their own wiki page. Have students include useful and unique information about each geographical area.
  10. Fact Checking
    The reason why wikis is often blacklisted as a reputable source is because not everyone who contributes to a wiki page is an expert. Keep your students on their toes by assigning them to fact check each other’s work.
  11. Riddles
    Encourage teamwork by posting riddles and having groups of students solve them through online collaboration. The students will use a forum to discuss what the possible answer is.
  12. Group Assessments and Tests
    As an alternative way to administer assessments, consider using wiki group assessments.  Students work together, helping one another to achieve success.

The objective of the paper is to modify the existing process capability index (PCI) for a Weibull distribution and to construct bootstrap confidence intervals (BCIs) for the newly proposed index. Three BCIs that consist of standard, percentile and bias-corrected percentile bootstrap (BCPB) confidence intervals are constructed for the newly proposed index and the existing Pearn and Chen index.
