According to Louann Brizendine, author of The Female Brain, women say nearly three times as many words per day as men. Skeptical researchers devised a study to test this claim. They used electronic devices to record the talking patterns of 396 university students who volunteered to participate in the study. The device was programmed to record 30 seconds of sound every 12.5 minutes without the carrier鈥檚 knowledge. According to a published report of the study in Scientific American, 鈥淢en showed a slightly wider variability in words uttered.... But in the end, the sexes came out just about even in the daily averages: women at 16,215 words and men at 15,669.鈥漒(^{56}\) This difference was not statistically significant. What conclusion can we draw from this study? Explain.

Short Answer

Expert verified
The study does not support Brizendine's claim; both sexes speak a similar number of words daily.

Step by step solution

01

Understanding the Research Claim

The initial claim by Brizendine suggests that women use nearly three times as many words as men per day. This study was conducted to test that claim.
02

Reviewing the Study Methodology

Researchers recorded talking patterns by using electronic devices on 396 university students. These devices recorded 30 seconds of sound every 12.5 minutes without the students knowing, eliminating biases from self-reporting.
03

Analyzing the Study Results

According to the results, women spoke an average of 16,215 words and men spoke an average of 15,669 words per day. These numbers are quite similar, and the difference is negligible.
04

Understanding Statistical Significance

The study explicitly mentions that the difference in word count between men and women was not statistically significant. This means that any difference could have occurred by chance and is not a strong enough difference to support the claim.
05

Drawing the Conclusion

Based on the results, the study does not support Brizendine's claim that women speak three times as many words per day as men. In fact, both genders seem to speak a similar number of words daily, contradicting the original assertion.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Research Methodology
Research methodology is the backbone of any scientific study, serving as the roadmap that guides researchers through their investigation. To understand the claim about gender differences in speech, it was crucial to use a methodology that ensured unbiased results.
Its main components involved the selection of participants, data collection, and analysis strategies.
In this study, researchers chose to include 396 university students as their sample, using an electronic device to objectively record speech patterns.
- This approach minimized participant bias, as the students were unaware when the device recorded their speech. - Using electronics for data collection is advantageous as it provides consistency and removes human error associated with self-reporting.
The device functioned discreetly, capturing ambient speech data every 12.5 minutes. This systematic approach ensured that speech was recorded at regular intervals throughout the day, providing a comprehensive picture of daily word usage. Recording methodology is key to gathering authentic data. When conducting research on behavioral patterns such as speech, eliminating direct influence from participants' awareness is vital for obtaining reliable results.
Gender Differences
Exploring gender differences in communication patterns is an intriguing area of research. The study at hand aimed to address a provocative claim: women purportedly speak nearly three times as many words as men daily.
However, the results told a different story.
- The average word count for women was 16,215 words and for men 15,669 words. - Despite seemingly significant numerical differences, the daily verbal output of both genders appeared almost identical.
This finding challenges preconceived notions about gender and communication. It illustrates how stereotypes might not always align with empirical evidence. Understanding gender differences in communication requires a nuanced look at various factors, including social and cultural influences. While this study focused on word count, it's important to consider that communication extends beyond just the number of words spoken. Tone, context, and purpose also play vital roles in how individuals express themselves.
Data Analysis
Data analysis is a critical phase of any study, translating raw data into meaningful insights. In the context of this study, analyzing the word count data involved comparing the average words spoken by men and women to test the initial hypothesis.
The process involved statistical techniques to determine significance.
- Researchers found that the average difference in word count between genders was not statistically significant. - "Statistical significance" refers to the probability of a result not being due to chance.
In this study, despite the numerical difference, the overlap in word usage between men and women suggested that the observed difference could have occurred randomly. Statistical significance helps researchers ascertain whether their results genuinely reflect the population or are anomalies. Thus, in analyzing this data, the conclusion drawn was that the initial claim of a large disparity was not supported by the evidence. Such analysis is vital in distinguishing between real effects and random variability, ensuring that studies' conclusions are based on solid ground.

An experiment that claimed to show that meditation lowers anxiety proceeded as follows. The experimenter interviewed the subjects and rated their level of anxiety. Then the subjects were randomly assigned to two groups. The experimenter taught one group how to meditate and they meditated daily for a month. The other group was simply told to relax more. At the end of the month, the experimenter interviewed all the subjects again and rated their anxiety level. The meditation group now had less anxiety. Psychologists said that the results were suspect because the ratings were not blind. Explain what this means and how lack of blindness could bias the reported results.

Select the best answer When we take a census, we attempt to collect data from (a) a stratified random sample. (b) every individual selected in an SRS. (c) every individual in the population. (d) a voluntary response sample. (e) a convenience sample.

Select the best answer Can changing diet reduce high blood pressure? Vegetarian diets and low-salt diets are both promising. Men with high blood pressure are assigned at random to four diets: (1) normal diet with unrestricted salt; (2) vegetarian with unrestricted salt; (3) normal with restricted salt; and (4) vegetarian with restricted salt. This experiment has (a) one factor, the type of diet. (b) two factors, high blood pressure and type of diet. (c) two factors, normal/vegetarian diet and unrestricted/restricted salt. (d) three factors, men, high blood pressure, and type of diet. (e) four factors, the four diets being compared.

Biological measurements on the same species often follow a Normal distribution quite closely. The weights of seeds of a variety of winged bean are approximately Normal with mean 525 milligrams (mg) and standard deviation 110 mg. (a) What percent of seeds weigh more than 500 mg? Show your method. (b) If we discard the lightest 10% of these seeds, what is the smallest weight among the remaining seeds? Show your method. Exercises 100 and 101 refer to the following setting. A researcher studied a group of identical twins who had been separated and adopted at birth. In each case, one twin (Twin A) was adopted by a low-income family and the other (Twin \(\mathrm{B}\) ) by a high-income family. Both twins were given an \(\mathrm{IQ}\) test as adults. Here are their scores: \(^{47}\) Twin A: 120 99 99 94 111 97 99 94 104 114 113 100 Twin B: 128 104 108 100 116 105 100 100 103 124 114 112

A football coach hears that a new exercise program will increase upper-body strength better than lifting weights. He is eager to test this new program in the off-season with the players on his high school team. The coach decides to let his players choose which of the two treatments they will undergo for 3 weeks鈥攅xercise or weight lifting. He will use the number of push-ups a player can do at the end of the experiment as the response variable. (a) Which principle of experimental design does the coach鈥檚 plan violate? Explain how this violation could lead to confounding. (b) Comment on the coach鈥檚 choice of response variable.
