### Examining the Differences in Word Recall
In this study, participants were tasked with recalling two different types of words: swear words and neutral words. The gathered data and subsequent statistical analysis are presented below.
#### Raw Data:
The table below summarizes the number of words recalled by each participant in two categories: swear words and neutral words.
\[
\begin{array}{|c|c|c|}
\hline
\text{Participant} & \text{Swear Words} & \text{Neutral Words} \\
\hline
1 & 94 & 59 \\
2 & 70 & 61 \\
3 & 52 & 47 \\
4 & 83 & 60 \\
5 & 46 & 35 \\
6 & 117 & 92 \\
7 & 69 & 53 \\
8 & 39 & 30 \\
9 & 51 & 56 \\
10 & 73 & 61 \\
\hline
\end{array}
\]
#### Descriptive Statistics:
For both types of words, the following statistics were calculated:
- **Count (n)**: The number of participants, which is 10 for each category.
- **Mean**: The average number of words recalled.
- Swear words: 69.4
- Neutral words: 55.4
- **DEVSQ(SS)**: The sum of the squares of the deviations (also known as the sum of squares).
- Swear words: 5182.4
- Neutral words: 2574.4
- **STDEV.S**: The standard deviation of the sample.
- Swear words: 25.41653005
- Neutral words: 17.81697069
#### Inferential Statistics:
An independent t-test was conducted to compare the mean number of swear words recalled to the mean number of neutral words recalled, which involves the following parameters:
- **df**: Degrees of freedom, which is 9 for both categories.
- **\(S_{M1-M2}\), alpha, \(t_{\text{crit}}\), \(t_{\text{obs}}\), Cohen's d, r²**: Placeholder values left for calculating specific statistical outcomes, which were used to reach a decision on the hypothesis](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe5f49087-22ae-4ef1-b91b-6905f9f28b09%2F95357bb7-8558-4335-b026-626f4a0153cf%2Fanubxv6_processed.jpeg&w=3840&q=75)
