Statistics- Methods Participants Individuals who participated
MethodsParticipantsIndividuals who participated in this study were all undergraduate students from variouscolleges. Students were specifically selected from psychology courses and were required toparticipate for class credit. The participant data was stratified into men and women and fromthere, a total of 40 participants was selected. Equal group sizes were formed with one groupconsisting of 20 men and another group consisting of 20 women. All participants ranged from 18to 64 years of age with the average participant being 31.5 years old. Participants in the group ofwomen ranged between age 18 and 64 with the average participant being 36.8 years old, whereasparticipants in the group of men ranged between 18 and 49 with the average participant being26.2 years old.MaterialsThis study was conducted via an online lab in which participants needed access to acomputer. In addition, participants needed computer speakers or headphones prior to beginningthe experiment. The online lab provided an unlimited sequence of numbers with the length ofsequences consecutively increased by one digit after each sequence length was presented twice.Spreadsheet software was also implemented to download and sort the data that had beencollected by the online lab.ProcedureIndividuals who volunteered for this study were directed to an online lab in which theycould participate in the experiment. Participants needed to make sure they had either computerspeakers or headphones before beginning the experiment. Additionally, participants wereinstructed to ensure the volume on their computer was turned up to an appropriate level. Theywere given a unique user identification number so their results could be identified. Participantsthen signed a consent form informing them of their experiment and detailing the task they wereto complete. Following this, participants were asked to provide their age and gender beforeproceeding to the experiment. Participants were given a practice trial in which they heard asequence of numbers and were then asked to enter those numbers in the same order back into thebrowser by using their mouse to click on the numbers they had heard. After the practice,participants could click to begin the experiment whenever they made any necessary adjustmentsto volume or monitor brightness. The first sequence presented contained one digit and waspresented twice. Each following sequence had one digit added to the length and was alsopresented twice. If participants correctly remembered digits in only one of the two sequences persequence length, the next sequence length was presented to them. The online lab continuedadding one digit to sequence length until the participant incorrectly entered both sequences for aparticular sequence length. Once this occurred, the experiment was concluded and participantswere given their score. The highest number of digits remembered by participants was recorded astheir score. Once data was collected from various psychology course students, the data wasstratified into men and women categories. From each category, 20 participant data were selectedand analyzed.ResultsIt was found that the average number of digits remembered by women and men werevery similar with the women at ( M =7.05, SD=2.31 ) and the men at ( M =7.15, SD=3.13 ) .Overall, men and women appeared to have similar digit recall when presented with auditorysequences of numbers as each group had roughly the same number of participants per digitlength remembered. These comparisons are presented in Figure 1 âClustered Column ChartShows the Frequency of Digits Remembered by Men and Women Following an AuditoryPresentation of Number Sequencesâ.Furthermore, it has been found that 75% of the values fall within one standard deviation of themean, 95% of values fall within two standard deviations of the mean, and 100% of values fallwithin three standard deviations of the mean for the sample group of women. This data set isrepresentative of a normal distribution. Similarly, it was found that 80% of the values fall withinone standard deviation of the mean, 95% of values fall within two standard deviations of themean, and 100% of values fall within three standard deviations of the mean for men â alsorepresenting a normal distribution.
