A chemist is performing four experiments and each experiment has five results. The results for each experiment are given in the following table. An experiment is considered successful if the average of the five test results for a given experiment is between 25 and 32. Using a nested loop, write a script that (Python):

- Compute and display the test results average for each experiment

- Indicate is the experiment was successful or not

1st Results 49.1 15.8 16.9 25.2 33.4
2nd Results 34.8 45.2 27.9 36.8 23.4
3rd Results 26.4 16.8 10.2 15.8 18.9
4th Results 26.9 19.5 42.9 42.5 27.4

Hint : Use lists to store each experiment results and a single list to store the entire table

Q1 . The authors cite the explanation of Thomas Kuhn (author of The Structure of Scientific Revolutions) of how a change of 'looking at the world' (Khun's term is "paradigm shift") within the practice of science takes place. The authors compare the views of Copernicus and Ptolemy regarding the structure of our solar system as an example:

a.Copernicus and Ptolemy used the same assumptions to organize a different set of facts and came to the same conclusion.

b.Copernicus and Ptolemy used different assumptions to organize a different set of facts and came to the same conclusion.

c.Copernicus and Ptolemy used different assumptions to organize the same set of facts and came to different conclusions.

d.Copernicus and Ptolemy used the same assumptions to organize a different set of facts and came to different conclusions.

Q2. "So how do scientists learn these organizing ideas? The usual way is by studying with other people who know what they're doing." Which of the choices below is the correct set of parts of speech for describing the term?

a."Organizing" is an adjective, "ideas" is a noun.

b."Organizing" is a verb, "ideas" is a noun.

c."Organizing" is a gerundive, "ideas" is a synecdoche.

Q3. Quoting the authors, "Technically, a paradigm is

a.how one goes about organizing ideas in a particular way."

b.what the study of anthropology is all about."

c.the cultural code that makes the example make sense."

Q4. Malinowski enumerates his "three principles of method" that he found leads to "success" in one's ethnographic research. (Identify the choice that does not belong.)

a.The student should have earned an advanced degree in anthropology from Cambridge or Drexel.

b.The student must approach the study scientifically, and know the values and criteria of modern ethnography.

c.The student ought to live alone with the natives, without other Westerners around.

d.The student has to apply a number of special methods of collecting, manipulating, and "fixing" the evidence that has been gathered.

Q5. Quoting Malinowski: "Our considerations thus indicate that the goal of ethnographic field work must be appreciated through three avenues:     (Identify the choice that DOES NOT belong)

a.The organization of the tribe, and the anatomy of its culture...

b.The organizing ideas that determine the cultural codes of the tribe.

c.the imponderabilia of actual life and the type of behavior have to be filled in.

d.A collection of ethnographic statements...as documents of native mentality.

"He should not have built the fire under the spruce tree. He should have built it in the open. But it had been easier to pull the twigs from the brush and drop them directly on the fire. Now the tree under which he had done this carried a weight of snow on its boughs. No wind had blown for weeks, and each bough was fully freighted. Each time he had pulled a twig he had communicated a slight agitation to the tree - an imperceptible agitation, so far as he was concerned, but an agitation sufficient to bring about the disaster. High up in the tree one bough capsized its load of snow. This fell on the boughs beneath, capsizing them. This process continued, spreading out and involving the whole tree. It grew like an avalanche, and it descended without warning upon the man and the fire, and the fire was blotted out!"

Activity 4: Experiment (YOU PRETEND TO DO THIS EXPERIMENT)

The control group in an experiment is the group who does not receive any treatment and is used as a benchmark against which other test results are measured. A control group is used in an experiment as a point of comparison, so that it can be isolated in testing that the experiment did, or did not, have the intended effect.

For example, scientists have developed many tests using reagents (substances used to detect another substance) to identify the different biomolecules. In order to perform these tests correctly, two different treatments must be completed to provide standards for comparison. The first treatment is called a positive control and contains the variable being tested for. The second treatment is the negative control, which does not contain the variable being tested for. To make sure your testing chemicals are not contaminated and to see what a negative reaction to the test will look like.

  • Exercise 3: Identify the parts of the experiment.   A researcher wants to find out if spraying fruits and vegetables with pesticides affects the vitamin levels in those foods.

     a) the independent variable: _______________________________________

     b) the dependent variable: _____________________________________

     c) two possible controlled variables: ________________________________

     d) the control group:   ___________________________________________

     e) the experimental group: __________________________________________

Activity 5: Data

Data are reported in objective terms that allow for independent interpretation by anyone reading the report. The preferred method of reporting data is the presentation of results in tables and graphs that provide a quick and clear overview of any observed effects. There are two types of data: qualitative and quantitative.    

Qulitative data include qualities such as color, smell and taste. These are subjectively perceived and can be difficult to express in an objective manner. While everyone conducting the experiment may agree that the solution changed color, there may be variation in what individuals identify as blue, light blue, etc.

Quntitative data include qualities that can be measured objectively such as weight, volume, length and temperature. Quantitative data have a number associated with them and can be reported in universally accepted measurable units. This makes it easy for others to interpret the results. Both types of data are valid and important. In some instances an experiment may result in just one or the other type of information. Frequently, the investigator may collect and report both types of data.

Exercise 4: Label the following as qualitative (L) or quantitative (N).

Temperature of 23 °C _____

Increase in color intensity _____

pH values _____

Bitter taste _____

Sound increase _____

Measurement of nitrates _____

Number of deaths _____

Precipitation _____

Sweet smell _____

Level of diversity _____

Activity 6: Results/Analysis

To understand data better, it is usually shown in some type of graphical format. The same data can be portrayed in different formats depending upon what is being emphasized. A pie chart shows the proportions of different categories (qualitative data). The amount of the pie (circle) correlates to the percentage. It can be as simple as just two categories or it can contain several categories. The more categories a chart has the more difficult it is to read. If there are many categories that have small numbers they are frequently lumped into an “Other” category.

Exercise 5a:   Creating a complex pie chart. Create a pie chart for a characteristic with at least four categories but not more than six. Choose a characteristic that varies among students. Appropriate examples include shoe type, color of pants, mobile phone service, or type of car owned. Each student should pick a different characteristic. To make data collection easy and fun, one by one students should introduce themselves to the entire class and the rest of the class can ask them about the characteristic they chose. Fill in the chart below and create a pie chart with your data.

The pier in Santa Monica, CA, is a popular destination for both tourists and locals. Visitors ride the Ferris wheel (F), eat ice cream (C), or just walk around on the pier (W). Write a dynamical model for the numbers of people engaged in these activities given the following assumptions. (Hint: Start by drawing a diagram of this system and labeling the stocks and flows. People entering the pier always start by just walking around. E people enter the pier each minute. Visitors leave at a constant per capita rate d. They can leave only when they are walking around. Due to fear of nausea, people do not go directly from eating ice cream to riding the Ferris wheel. Visitors prefer to go on the Ferris wheel with friends. Thus, the probability that any one individual will go on the Ferris wheel is proportional to the number of people walking around, with proportionality constant b. Riders leave the Ferris wheel at per capita rate n. When visitors leave the Ferris wheel, a fraction z of them go directly to eating ice cream. The others walk around. Visitors who are walking around prefer to avoid long lines for ice cream. Thus, the per capita rate at which they get ice cream is proportional to the inverse of the number of people already doing so, with proportionality constant m. People who are eating ice cream stop doing so at a constant per capita rate k.
