Coursework on Description Statistics

Descriptive statistics were performed to determine the frequency of group status, attachment, situational involvement, enduring involvement, identity resilience, satisfaction, attendance, and salaries of respondents. The analysis shows that all the respondents (100%, N=70) were parents. The majority of the respondents (17.1%, N=12) had a score of 25 on attachment. 11.4% had a score of 21 with a further 11.4% having a score of 39. The rest of the scores recorded less than 10% respondents each. On situational involvement, the majority (34.%, N=24) had a score of 48. Half of the respondents (50%, N=35) had an enduring involvement score of 27 while only 1.4% had a high score of 62. Most of the respondents (44.3%) who had identity resilience scored 10 and the highest score was attained by 1.4% of the participants. Regarding satisfaction, the overwhelming majority (54.3%) scored 12, 18.6% scored 11, and 18.6% had a score of 6. Only 1.4% attained a high score of 21. The highest attendance had a frequency of 1.4%; the majority, however, had a score of 22.9% (score of 12), 18.6% (score of 11), and 18.65% (score of 10). Moderate frequency (12.9%) of attendance was also noted for respondents who scored 5. Out of the 70 respondents, the overwhelming majority of participants elected not to discuss their salaries. Each of the remaining participants had a salary different from the rest of the respondents.

Stem-and-Leaf Plots Distribution of Variables

The stem-and-leaf plots were produced to explore the scores of each of the respondents for all the variables. A stem and leaf display of the data is accompanied. The left portions of the figures contain the stems while the numbers to the right of the bar are leaves. For the group, all the respondents were parents. The stem-and-leaf plot does not follow a normal distribution. The stem-and-leaf plot of attachment scores does not show a normal distribution with the majority of the scores eschewed towards the lower scores. Figure 4 shows an abnormal distribution of situational scores with the majority being at the score of 59 and below. As far as enduring involvement is concerned, the scores are not normally distributed with most of the scores heavily skewed towards a score of 43 and below. The identity salience scores do not meet the criterion of a normal distribution because the distribution of the scores appears like a dome shape that is skewed toward the lower scores. The stem-and-leaf plot of satisfaction scores does not show a normal distribution with the majority of the scores skewed towards the lower scores 13 and below. The attendance scores do not meet the criterion of a normal distribution because the distribution of the scores appears like a dome shape that is skewed toward the higher scores, the lowest attendance score being 5 and the highest being 21. Finally, the stem-and-leaf plots the respondents' salaries show an abnormal distribution with the lowest earning 10,000 and the highest 110,000 (9). In a stem-and-leaf plot, data is said to be normally distributed if the data forms a perfect dome-shaped distribution around the middle.

Regression Analysis

Prediction model: (Y = bo + b1X1 + b2X2 + b3X3 + b4X4). Where, Y = attendance, X1 = identity salience, X2 = attachment, X3 = enduring involvement, and X4 = situational involvement.

A regression analysis was conducted to predict attendance based on the respondents identity salience, attachment, enduring involvement, and situational involvement (independent variables). Overall, the regression model was statistically significant (F (4, 65) = 79.340, p= 0.000). Identity salience, attachment, and situational involvement were the statistically significant predictors of attendance. In addition, situational involvement was inversely related to the dependent variable, attendance. However, enduring involvement was not a statistically significant predictor of attendance. The coefficient of correlation (r) indicated a strong relationship between the independent variables and attendance (r = 0.911). A model fit index, the coefficient of determination (R2), was 0.83, indicating that 83 percent of the variation in attendance can be attributed to identity salience, attachment, and situational involvement. The adjusted R2, which considers the number of predictors and the sample size, was 0.820, which indicated no extraneous predictors were included in the model. Because the standard error of the estimate was 1.330, the prediction equation performed satisfactorily.
