Document Summary

X-axis is retention interval (days) and y-axis is savings or % of information you can recall (how much you can recall) At immediate recall we are 100% accurate, no information forgotten. After 20 minutes, there is a large drop in information, approx. After an hour we are down to 40% retained meaning 60% was lost. After by day 2 we are close to 20 but it plateaus here (80%) It is a quadratic function, meaning huge loss of information at beginning and it plateaus for ebbinghaus curve. Typically people can recall easily the first and last words in a list, but the words in the middle tend to be forgotten. Primacy effect - is why you are better at recalling worse at the start of the list (couch knife fish). When seeing those words first, you are able to rehearse them for longer.

can anyone help with this really super basic lab? Feel free tomake up data, highschool level information please!

You are NOT limited to the suggested projects listed below.Think up your own unique research project!!

Projects should involve observation/measurement of livingorganisms-plants, animals, fungi, humans. They should be designedto answer a question or to test a hypothesis. Examples ofhypotheses would be; "Plants will grow more if there is morerainfall" Or "Students will get higher grades if they study more."Sample size is important when possible; make multiple measurementsof several individuals. Your project must be something thatproduces DATA that can eventually be graphed. There should be adependent variable and an independent variable. For example,"amount of rainfall" would be an independent variable and "how fastplants grow" the dependent variable.

Projects should take approximately three hours, total, tocomplete, not counting the write up, which will be a separate lab.Detailed instructions on writing your report are attached. Keepyour project simple and manageable. Submit your first project bythe due date for Project 12 (July 7th)**Please make sure that yourassignment gets to me by the due date. You will still be able toupload your assignment after the due date, but it will be marked aslate, and you will lose some points for being late.

A few examples of projects:

Is there a correlation between the size of a dog, and how longit lives? For this you will need about ten dead dogs! Ask aroundamong friends, classmates, family, about dogs that died a naturaldeath. Find out each dog's age at death, and approximate weight. Alarger sample size here would be even better. Can you explain thecorrelation?

Do humans have a physiological response (difference in pulse,blood pressure, etc.) to music? Choose three different categoriesof music, such as classical, folk, rock, or none (silence). Have atleast five people in your study, and measure their pulse (or bloodpressure) both before and after they have listened to the music for5-10 minutes. Graph the increase (or decrease) in their pulse forthe different types of music. GRAPH THE AVERAGE values for yoursubjects, not value for each individual.

Is there a correlation between a person's usual amount of sleep,and how well they perform on memory tasks? Devise a SIMPLE memorytest-it could be just to study a list of twenty random words, andthen to recall as many as possible. Give this test to at least fourpeople who usually get (a) less than 6 hours sleep, (b) 6-7 hourssleep and (c) 8 or more hours. Or, choose your own categories.Amount of sleep is your independent variable (X axis) and AVERAGEscores on the test, the dependent variable. (Y axis). GRAPH THEAVERAGE!

Include ALL relevant observations and information in precisedetail. If possible, include illustrations of your experiment, yoursubjects, your work in progress, etc.

Background When you look at news reports of any kind, there can be a tendency to take them at face value, accepting what they tell us as the truth. This is usually a grave mistake. News typically moves quickly, with tight deadlines to get information and there is almost always a bias at play. Numbers are an easy way to manipulate the truth--and truth itself can be pretty flexible when it comes to human relationships. The value of the truth can also be flexible depending on your point of view. For example, in the second quarter of 2015, the U.S. dollar is strong--meaning it has a high value against foreign currency. Is this a good thing or a bad thing? If you're a consumer, it's generally a good thing in the short-term. It means items imported to the U.S. cost us less to buy. Go us! If you are a growing business that exports, it's a bad thing because your costs make it difficult to compete with locally produced goods in foreign markets. If you're traveling out of the country, it's good because the dollar goes farther. If you have a business that benefits from foreign tourism, it's bad because visitors have less money and may chose to go to other places where their money gives them more buying power.

find an article (you might try MSN Money or CNN Money or something similar) and then write at least 600 words. how strong the position the article takes is. Questions to consider include: What are the weaknesses to the article? How are numbers used effectively? What's missing? How are the numbers being used to disguise something?

ARTIcle

President Obama slapped a stiff 35% tariff on Chinese tires in 2009 after American companies complained about unfair competition. They said China was flooding America with tires at low prices making it tough for U.S. companies to compete. The tire tariff gradually waned, and finally ended in 2012. The tariff saved 1,200 U.S. tire jobs, which had been in sharp decline. And U.S. tire production rose after a major decline. "Over a thousand Americans are working today because we stopped a surge in Chinese tires," Obama said in his 2012 State of the Union address. But a study from the Peterson Institute of International Economics found that the tariffs cost Americans in many other ways. Americans paid more for tires. Some Chinese-made tires cost as much as 26% more -- rising on average to $39 per tire, from about $31. And U.S. tire makers, facing less competition from China, also raised prices on American-made tires 3.2%. According to Peterson's model, higher prices from the tire tariff cost Americans an extra $1.1 billion, which translated to an estimated 3,731 retail jobs lost. Plus, China fought back by imposing penalties on U.S. shipments of chicken parts. The Peterson study estimates that China's retaliation cost American chicken producers $1 billion in sales. "Tire safeguards did not change Chinese policies in a helpful way, nor did they boost U.S. employment," wrote Gary Hufbauer, a trade expert at Peterson, who authored the report. Indeed, the tariffs didn't bring the tire-making jobs back to previous levels -- a similar trend that's played out for the rest of U.S. manufacturing. But they did help to stem the job losses. In 2008, there were about 60,000 American workers making tires. Now, there are about 55,000. That's better than the low point reached in 2010 but not back to pre-tariff levels. Related: Trump's 35% tariff on companies: Easier said than done An Obama administration official, who requested anonymity, disputed some of the calculations and assumptions in the Peterson study. For instance, the official claimed tire prices did not go up by as much as the study claims. Hufbauer said no one until now had contested any of his analysis in the four years since it was published. He noted that the administration official didn't provide an alternative estimate for price changes. Republican presidential nominee Mitt Romney criticized Obama for the tariffs in his 2010 book "No Apology." "President Obama's action to defend American tire companies from foreign competition may make good politics by repaying unions for their support of his campaign, but it is decidedly bad for the nation and our workers," Romney said. U.S. tire makers still applaud Obama's tariffs. Morry Taylor, CEO of Titan International, a U.S.-based tire company, is one of them. "He did what he should have done and he should have done more of it," says Taylor, who voted for Trump. His company has plants in Ohio, Wisconsin and Illinois (they also have operations in Brazil and Russia). Related: 3 ways Trump can go after China and Mexico Taylor argues that if the tariffs weren't put in place he might not have any business today to speak of. By 2012, Taylor still had 1,800 tire-making workers, about the same amount as before the tariffs. Today, however, his firm only has a little more than 900 workers. His problem today is what he describes as unfair competition from India, where firms make cheap tires and sell in the U.S. at prices he can't afford to sell at. He hopes Trump considers higher tariffs on tires, saying it would save jobs. To be clear, Obama wasn't trying to "bring back jobs" so much as protect the ones already in America, which he accomplished. Trump wants to bring manufacturing jobs back from other countries. Some trade experts believe that would be difficult task, since many of jobs overseas are low-skill positions and many U.S. manufacturing firms now want highly skilled employees. In any case, U.S. tire production recovered but didn't surge. Instead, U.S. tire imports from all other countries excluding China rose dramatically, Hufbauer found. In other words, the Chinese tire jobs didn't come to the U.S. -- they went to the next cheapest countries. In the end, Hufbauer argues the tariffs didn't make a difference. "The best thing about the tire tariffs is that they expire," Hufbauer wrote in 2012. CNNMoney (New York) First published January 3, 2017: 3:41 PM ET
