Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

A study found that dealing with 'infomania' has a temporary but significant
derogatory effect on IQ (2005). Researchers divided volunteers into three groups,
and each volunteer took an IQ test. One group had to respond to emails and texts
at an average rate of 1 every 5 minutes, one group had to respond to emails and
texts at an average rate of 1 every 2 minutes, and the last group had no
distractions. The research was also curious about the effect of age.
3.
a)
Identify the factor(s).
b)
What is the response variable(s)?
c)
Identify the treatment(s).
d)
Identify any blocking variables.
e)
Sketch a diagram representing this experiment.
Just in case you are curious, the middle group experienced on average a 10 point decline
in IQ, and the highly distracted group experienced on average a 15 point decline in IQ.
Just saying....

What is an experiment?
The Institute of Psychiatry at Kings College London found that dealing with infomania (information overload) has a temporary, but significant derogatory effect on IQ.† Researchers divided volunteers into two groups. Each subject took an IQ test. One group had to check e-mail and respond to instant messages while taking the test, and the second group took the test without any distraction. The distracted group had an average score that was 10 points lower than the average for the control group. Explain why it is important that the researchers created the two experimental groups in this study by using random assignment. O Without random assignment, the researchers cannot make multiple observations for each group. O Without random assignment, the researchers can't hold extraneous variables constant. O Using random assigment ensures the conclusion can be generalized to a larger population. O Using random assignment produces comparable, unbiased experimental groups. O Using random assigment…

Lake Martin and Lake Fields are two large local lakes inhabited by white sturgeon. A while back there was an environmental disaster at Lake Martin. Kala is an ecologist who wants to see if the mean weight (in kg) of adult white sturgeon now living in Lake Martin is less than the mean weight (in kg) of adult white sturgeon now living in Lake Fields. The ecologist catches a random sample of 11 adult white sturgeon at Lake Martin and a random sample of 12 adult white sturgeon at Lake Fields. (These samples are chosen independently.) Each fish has its weight (in kg) recorded. The white sturgeon caught at Lake Martin have a sample mean weight of 90.24 with a sample variance of 15.11. The white sturgeon caught at Lake Fields have a sample mean weight of 98.52 with a sample variance of 231.20. Assume that the two populations of weights are approximately normally distributed. Can the ecologist conclude, at the 0.01 level of significance, that the population mean of the weights of adult white…
An und Tuate student performed a visual experiment on a number of participants. Since the experiment involved displays of colored letters and backgro after the experiment the student wondered whether the presence or absence of color vision in the participants could have produced some of the effects seen in the data. The student went back, tested his participants for colorblindness, and reanalyzed the data. He considered the variables color vision of participant ("colorblind" or "not colorblind") and trial outcome ("hit", "miss", "false alarm", or "correct rejection"). The contingency table below gives a summary of the data from 2000 trials of the experiment. Each of the trials was performed either by a colorblind participant or a non-colorblind participant. Each cell of the table contains three numbers: the first number is the observed cell frequency (f); the second number is the expected cell frequency (f) under the assumption that there is no dependence between the two variables…
Harker and Keltner (2001) examined whether emotional well-being in later life could be predicted from the facial experience expressions of 141 women in their college yearbook photos. The predictor variable of greatest interest was the “positivity of emotional expression” in the college yearbook photo. They also had these photographs rated on physical attractiveness. They contacted the same woman for follow-up psychological assessments at age 52 (and at other ages, data not showing here). Here are the correlations of these two predictors (based on ratings of the yearbook photo) with several of their self-reported social and emotional outcomes at age 52: In College Photo At Age 52 Physical Attractiveness Positivity of Facial Expression Negative emotionality .04 -.27 Nurturance -.06 .22 Well being .03 .27 Which of the six correlations above are statistically significant (i) if you test each correlation using = .05, two-tailed, and (ii) if…

A research team is interested in determining if there is a relationship between death anxiety and religiosity. Subjects completed a death anxiety scale (high score = high anxiety) and also completed a checklist designed to measure an individual's degree of religiosity (belief in a particular religion, regular attendance at religious services, number of times per week they regularly pray, etc.) (high score = greater religiosity). What statistical test is most suitable to answer the research objective? a. Chi-Square Test b. Correlation Coefficient c. t-test d. ANOVA
The administrators of a Faculty A were interested to understand personal characteristics of their students. They decided to conduct a survey and managed to get randomly 1625 students to respond to the survey. The same survey has been conducted for 3 years in a row and a summary report on students’ characteristics was produced. The first part of the survey was asking demographics questions on the students. The data in Table 1 show eight variables, each describing a different characteristic of the students taking the survey. For the data in the table, the description of the data is as follows: ID : An identifier for each of the individuals in the study. Gender : M for male and F for female Mathematics : To measure how much the student likes Mathematics courses (Really Don’t Like it, Not too much, I like it, Absolutely love it) Exercise : Number of times spent exercising per week Games : Number of hours spent playing online games per week GPA…
A research study was conducted about gender differences in "sexting." The researcher believed that the proportion of girls involved in “sexting” is less than the proportion of boys involved. The data collected in the spring of 2010 among a random sample of middle and high school students in a large school district in the southern United States is summarized in Table. Is the proportion of girls sending sexts less than the proportion of boys "sexting?" Test at a 1% level of significance. Table 2: Frequency of "sexts" sent by gender Gender Males Females Sent "sexts" 183 156 Total number surveyed 2231 2169

A sleep researcher wants to determine whether a new pillow might reduce snoring amongst patients with this type of sleep apnea. Participants are randomly assigned to use the new pillow or a control condition (regular pillow). Their sleep behavior is recorded on audiotape with time snoring. The findings indicate significantly less snoring takes place with the new pillow. Identify the independent variable (and categories) and the dependent variable. Explain a Type I error in terms of this study. Explain a Type II error in terms of this study.
