To investigate how psychological and educational researchers have statistically handled ceiling/floor data in post-hoc methods for multiple comparisons, a brief literature review was conducted.
I collected 200 English articles published within a
five-year span that mentioned “ceiling effects” or “floor effects,” illustrating the presence of ceiling and floor effects in
the literature. Among the articles, we focused on reviewing
those that were published in journals with higher impact factors (i.e., five-year impact factor > 2). As examples, we
reviewed articles from the Journal of Experimental
Psychology, Psychological Science, American Educational
Research Journal, and Child Development. 
After excluding papers focused on methodology and literature review, the review of post-hoc methods for multiple comparisons and handling of ceiling/floor effects in the 60 sources revealed diverse approaches. Most studies utilized specific post-hoc methods to address multiple comparisons. Bonferroni corrections were prominently used, appearing in 15% (9 studies) of the cases. Notable examples include cite{peterson2019saccadic} and cite{herde2022retinotopically}, who applied Bonferroni corrections to correct for Type II error. Other methods, such as Tukey’s HSD, were employed in 13.33% (8 studies) of the cases. Holm-Bonferroni corrections were used in 21.6% (13 studies). Notably, the studies using Holm-Bonferroni and Bonferroni corrections did not specify the tests used, such as Scheffé, Tukey HSD, or pairwise t-tests. Additionally, methods like Sidak-adjusted pairwise comparisons and Student–Newman–Keuls tests were also observed, reflecting tailored strategies to meet the unique demands of each study. 
Handling ceiling and floor effects varied significantly across the studies. 8.33 % (5 studies) noted their ceiling/floor data percentages, with cite{newman2019effects} mentioning a potential ceiling effect in 3% of the data. Approximately 76.66% (46 studies), including cite{huggins2021autistic}, chose to ignore potential ceiling or floor effects, either due to their minimal impact or through acknowledgment without specific adjustments. In contrast, 24.33% (14 studies) took active measures to mitigate these effects. Specifically, 6.66% (4 studies) removed ceiling/floor data. For instance, cite{chierchia2020prosocial} employed data truncation to address skewed results. Furthermore, 13.33% (8 studies), including cite{senftleben2021stay} and cite{samuel2020reduced}, repeated their experiments to validate their findings. Notable examples include cite{adams2021introspective}, who addressed floor effects by increasing the overall magnitude of oculomotor capture effects by color singletons in Experiment 2, and cite{wiesmann2022makes}, who repeated the experiment with more controlled viewing conditions and added various stimulus conditions and SOAs to diversify task difficulty levels. Despite the changes, ceiling effects was still observed but at a reduced rate. Therefore, they also used generalized linear mixed models (GLMMs) for detailed statistical analysis to compare performance across different conditions, allowing for more meaningful findings despite the remaining presence of ceiling effects. Additionally, 2 studies employed other methods to handle ceiling/floor effects. cite{shepherdson2018working} address ceiling effects indirectly by using a hierarchical drift diffusion model (HDDM) that handles near-ceiling accuracy by including both accuracy and reaction time data, ensuring reliable parameter estimates despite high accuracy levels. The mathematical reasoning for choosing this method was not described. 
One notable study by citet{multisensory2020} has handled the ceiling effect by using a method that citet{macmillan1985detection} recommends which is to adjustments based on Signal Detection Theory (SDT). The sensitivity index (d’) is calculated using the z-transformed hit rate (z(H)) and false-alarm rate (z(FA)) with the formula:
begin{equation}
d’ = z(H) – z(FA)
end{equation}
When proportions are 0 or 1, adjustments are made by replacing 0 with (frac{1}{2N}) and 1 with (1 – frac{1}{2N}), where (N) is the number of trials. This ensures the proportions remain within a calculable range, avoiding infinite values in the z-transformation. Using these adjusted hit and false-alarm rates, the recalculated sensitivity index (d’) remains finite and accurate. This method was applied in the study citet{multisensory2020} to handle ceiling effects and ensure robust statistical analysis.

USA today provided a “snapshot” illustrating poll results from 21,944 subjects. The illustration showed that 43% answered “yes” to this question : ” Would you rather have a boring job than no job?” The margin of error was given as plus and minus 1 percentage point.
1. Describe what is meant by the statement that the “the margin of error is plus and minus 1 percentage point”.  
2. Also, we are given that 43% of 21,944 people polled answered “yes”. Given that 43% is the best estimate of the population percentage, why would  we need a confidence interval?   
Part II:
Find an article on public opinion survey data Links to an external site. based on your interest. Each of these studies report the percentage(s) of US adults agreeing with the given topic’s primary question(s). This percentage is the “sample proportion of success = phat”. Make sure to check that they report the sample size used in “How we did this” section (in rare instances, the sample size is not reported). Now use the sample proportion of success and the sample size to calculate a 95% confidence interval for the true population proportion. For the purpose of this discussion provide the following: 
In 100 words share the topic you have chosen and the motivation behind choosing this topic. Include the parameter of interest. Share the link of the survey article.
Clearly show the calculation of the confidence interval by indicating the value of n, p-hat, and z for a 95% confidence interval. Check conditions.
Explain what the interval means in context. 
2 Peer Responses due by Sunday, 7/14. The responses should thoughtfully address the topic being discussed in the article ( Some points you could talk about are : your personal motivation to respond to the topic; sampling method used and how it informs constructing a confidence interval requirements; what other questions could have added value to the topic; etc), the calculation of the interval and writing the interpretation.
(See an example below)
Confidence Intervals for Public Opinion on How Teens and Parents Approach Screen TimeLinks to an external site.
This Pew Research Center survey aimed to gather insight from US parents and their teens to better understand their experiences with screen time. I am a parent with a teen kid so I get to see kids these age at social gatherings, school events, playdates etc. and have noticed how quickly screen time and social media populated the lives of kids since when my oldest (who is in junior year of college) was in middle school. The study does a good job in gathering screen time use from both teens and parents alike. Interestingly enough, parents also tend to spend a lot of time on their phones and the trends are interesting when disaggregated by income and race and ethnicity. I am able to relate to the questions addressed in this study was happy to share it with my teen. In this example, I will focus on “Do parents think they spend too much time on their phone?”
Parameter of Interest: % of US parents of teens ages 13-17 who say the amount of time they spend on their smartphone is too much
Sample Proportion (p-hat): According to the survey, 47% of parents believe they spend too much time on their smart phones. This is our p-hat.
Confidence Interval (CI): I will find the 95% confidence interval for the true proportion of all US parents of teens ages 13-17 who say the amount of time they spend on their smartphone is too much.
n = sample size = 1,453
z-value for a 95% confidence level = 1.96
Checking Conditions:
Randomization condition: is met because participants were identified using a random sample of residential addresses.
10% condition: is met because the sample of 1,453 parents of teens ages 13-17 is less that all parents of teens ages 13-17 in the population
Success/Failure condition: is met because there are

Interpretation: We are 95% confident that the true proportion of all US parents of teens ages 13-17 who say the amount of time they spend on their smartphone is too much falls between 44.4% and 49.6%. 
As alarming as the dependence on smart phones may have become, it is clear that it is affecting people across all age groups. As parents and adults we should have a better understanding of habits that can send a wrong message to our teens and youth. Setting good examples is one of our responsibility that should not be ignored.

Discussion Question 2: Simpson’s Paradox In this project, we investigate an interesting phenomenon known as Simpson’s Paradox. A study on the survival rate of patients recorded whether hospital patients lived or died, which of two hospitals the patients were admitted to, and the condition (poor or good) of the patient when admitted to the hospital. One way to examine three categorical variables is to give multiple two-way tables: one for each category of the third variable. Tables 1 and 2 give two-way tables for the status and the hospital variables, with the subjects separated based on the condition on admittance. Table 1. Good Condition Hospital A Hospital B Died Survived 6 594 8 592ACTIVITIES AND ASSIGNMENTS FOR WEEK 2 Table 2. Poor Condition Hospital A Hospital B Died Survived 57 1443 8 192 Table 3. Let’s ignore the condition of the patient Hospital A Hospital B Died Survived (1) Considering only patients in good condition, which hospital has a lower death rate? (2) Considering only patients in poor condition, which hospital has a lower death rate? 3 (3) Which hospital is the best choice for good condition patients? Which hospital is the best choice for poor condition patients? (4) Suppose the researchers decided the condition of the patient was not relevant, and looked only at the two variables of the survival statusand the two hospitals. Complete Table 3 to include all patients (in either condition). (5) Use Table 3 to determine which hospital has a lower death rate. Is your result surprising? (6) Discuss the discrepancy in your answers to parts (3) and (5). This discrepancy is an example of Simpson’s Paradox, in which the existence of a confounding variable– in this case, the condition of the patient can actually reverse the interpretation of an observed effect. Which hospital really is the best choice? (7) Do a web search and find another example of Simpson’s Paradox. Give the details of the example and explain how it demonstrates this paradox.
