Your friend is taking an introductory statistics course and is now learning about linear regression. They are having a difficult time understanding how scatterplots, line-of-best-fit, Pearson’s r, residuals, squared residuals, outliers and R-squared relate to each other. Your friend says they are a “visual learner” and gets confused by all the calculations and R code. They think if only they could understand the big picture, maybe they would understand what each calculation and R command does.

While thinking of how to help your friend, you stumble across this website:(link: https://phet.colorado.edu/sims/html/least-squares-regression/latest/least-squares-regression_en.html ). This URL leads to a web application that allows you to create and calculate a scatterplot, a line-of-best-fit, residuals, squared residuals and Pearson’s r. It also shows you the regression equation. Best of all, this application operates in real time and lets you create custom scatterplots.

Prompt

Design three to seven screenshots and supporting text that allow you to demonstrate the following to your friend:

How the line of best-fit changes as new observations are added or removed.How outliers can impact the strength and direction of Pearson’s r.How Pearson’s r changes as new observations are added or removed.How the residuals (AKA error terms or deviations) change as new observations are added or removed.How better fitting lines produce smaller squared residuals.How better fitting lines produce higher values of Pearson’s r.How Pearson’s r (and R-squared, a measure of goodness-of-fit) is independent of the slope of the line.

Sample Solution
St. Patrick’s Day, in any event, for the Irish, is frequently covered in secret, or individuals once in a while think of it as important to look into the essentialness of this occasion. Generally, it is viewed as a day to sport green and get alcoholic at the bar with companions. Be that as it may, is there a more profound significance behind this Irish festival? So as to reveal the subtleties, the life of Saint Patrick will be talked about, also how the occasion appeared and how it is commended. Holy person Patrick is viewed as the first benefactor holy person of Ireland. Holy person Patrick is, “attributed with carrying Christianity to Ireland and presumably capable to some degree for the Christianization of the Picts and Anglo-Saxons. He is known distinctly from two short works, the Confessio, an otherworldly self-portrayal, and his Letter to Coroticus, a reprobation of British abuse of Irish Christians. Since his compositions have come to be better comprehended, it is progressively perceived that, in spite of their intermittent ambiguity, they reflect a reality and an effortlessness of the rarest quality” (O’Raifeartaigh, Tarlach). Thus, regardless of the numerous legends about him, he was a genuine individual that added to acquiring Christianity to the majority Ireland and for his simple to-peruse bits of composing. As to the legends, there are many. It isn’t astounding since he was such a significant figure in Irish history. The primary legend relates to him driving snakes to the ocean. Different legends are, “… that he raised individuals from the dead, and a twelfth century hagiography puts this number at 33 men, some of whom are said to have been perished for a long time. He additionally allegedly petitioned God for the arrangement of nourishment for hungry mariners going via land through a ruined territory, and a group of swine supernaturally showed up. Another legend, likely the most well known, is that of the shamrock, which has him clarify the idea of the Holy Trinity, three people in a single God, to an unbeliever by demonstrating him the three-leaved plant with one stalk” (O’Raifeartaigh, Tarlach). The trustworthiness of these cases can’t be confirmed, however they add to the enchantment of St. Patrick’s Day. St. Patrick’s Day denotes the holy person’s demise day, March seventeenth, 461 AD. In mid seventeenth century, this day was made into a dining experience day that is presently celebrated in the Catholic Church, the Anglican Communion, the Eastern Orthodox Church, and the Lutheran Church. As per Ireland.com, “Raise your glasses to Luke Wadding, an Irish Franciscan monk from Waterford whose industrious endeavors transformed March 17 into a gala day” (“9 St Patrick’s Day Facts”). In this way, Luke Wadding is the fundamental propagator of the banquet and at last the occasion. Formally, the festival celebrates the bringing of Christianity into Ireland and Irish culture by and large. In spite of the fact that strict Irish individuals may go to community gatherings on this day, it is additionally a merciful day where the prohibition on drinking liquor is frequently lifted. That is the reason the occasion is normally connected with drinking brew (Moore, Willard B.). In spite of the fact that Ireland unquestionably overplays St. Patrick’s Day, it is frequently the Irish diaspora in North America and different territories that maybe put on the greatest act. Marches, gatherings, naughtiness, and Irish pride is in plain view on March seventeenth in many urban communities of huge Irish populaces outside of Ireland. As far as marches, “the first St Patrick’s Day march was not held in Ireland by any stretch of the imagination, however in Boston in the United States in 1737. This was trailed by an “official” march in New York in 1766. Ireland was somewhat further behind – our first procession was held in Waterford in 1903, while Dublin joined the club in 1931″ (“9 St Patrick’s Day Facts”). Another fascinating actuality is that the wearing of green on this occasion just began in the nineteenth century, and before that time, for the most part individuals donned blue for the festival (“9 St Patrick’s Day Facts”). St. Patrick’s Day is a blissful festival of Irish legacy, culture, and all the more generally, the bringing of Christianity to Ireland. The custom of setting off to the bar, sporting green, and putting on marches came a lot later in its history, as it previously began as a strict gala in the seventeenth century, regardless of St. Patrick biting the dust in 461 AD.
