Survey datasets on the externalizing behaviors of primary school pupils and secondary school students in some selected schools in Ogun State, Nigeria.

This data article contains the partial analysis (descriptive statistics) of data obtained from 1770 primary school pupils and secondary school students in three Local Government Areas of Ogun State, Nigeria. The schools are either privately owned or public (government owned) schools. The aim of the field survey is to measure the level and patterns of externalizing behavior of the respondents. The data was collected using a standardized questionnaire. The questionnaire is a modification of Achenbach manual for Child behavior checklist (Achenbach, 2001) [1] and manual for Youth self-report (Achenbach and Rescorla, 2001) [2]. The questionnaire was designed to suit the demographic and socio-cultural nature of the target population. Analysis of the data can provide useful insights to the patterns of externalizing behavior of primary school pupils and secondary school students.

Value of the data

The data provide the descriptive statistics for the selected samples which gave an exploratory trend of the observed characteristics.

The data when completely analyzed can provide insight on the similarities and differences in patterns of externalizing behaviors of primary school pupils and secondary school students.

Researchers can gain more insight on the instrument of data collection, which can be adapted or adopted to suit the studied socioeconomic, demographic, psychographic and behavioral characteristics.

The questionnaire can be used for the study of the externalizing behavior of children and early adolescent youths.

The questionnaire can be adapted or adopted to include cohort and/or longitudinal studies.

The data could be useful in the following research areas: child behavior, adolescent health, early child education, guidance and counseling, mental health, psychiatrics, psychopathology, Developmental psychology, Multivariate Behavioral Research, Clinical Psychology and so on. The central theme is the study of externalizing behavior instincts and observed patterns between primary school pupils and secondary school students.

Most vulnerable groups obtained from data analysis can be singled out for counseling and monitoring by the concerned authorities thereby improving on the public health of the people.

Data

The data in this article is the set of responses solicited from 1770 primary school pupils and secondary school students in three Local Government Areas in Ogun State Nigeria. The details of the sample size are shown in Table 1a, Table 1b, Table 1c, Table 1d, Table 1e and 1f. The data was collected by the use of questionnaire. The questionnaire is a modification of Achenbach manual for child behavior checklist [1] and manual for youth self-report [2]. The nature and usefulness of the data entails that it can be analyzed using the following statistical techniques: regression analysis (ordinary least square), analysis of variance, Poisson regression, logistic models, path analysis models, latent growth curve analysis, middle level growth models, factor analysis, principal component analysis, multiple correspondence analysis, structural equation modeling, multivariate regression models, cluster analysis and so on.

The contents of the data are variables that determine the externalizing behavior of the respondents. These variables are as a result of under control of emotions as listed in the questionnaire. The analysis of the data can reveal the externalizing behavior of the respondents which can manifest as aggression, delinquency and hyperactivity. Furthermore, the gender, age and educational level differences in the distribution of externalizing behavior patterns can be obtained from the analysis of the data. In addition, research questions can be posed and statistical hypothesis can be tested based on the data. Finally, the data contains some variables which have not been considered in the analysis of externalizing behavior in children and adolescents and the questionnaire can serve as a benchmark tool for behavioral analysis especially in the sub Saharan region of Africa.

The data can be assessed as Supplementary data 1 and the Questionnaire can be assessed as Supplementary data 2.

The summary statistics was represented by a histogram shown in Fig. 1.

The histogram is the chart representation of the descriptive statistics. The histogram revealed the presence of fewer outliers (extreme behavioral patterns).

The percentage of the individual score compared with the total score

The percentage of the individual score compared with the total score can be computed using the formula;

The total score is 200. The summary statistics for this subsection is shown in Table 3.

Experimental design, materials and methods

Researches on externalizing behavior and other related fields are often conducted by the use of standardized questionnaires. Details on other research aimed at studying the nature, causes, distribution and management of externalizing behavior in children and adolescents can be found in [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30]. Sample (field) survey was used to obtain the data, similar researches that used field survey to obtain their data can also be found in [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], [42], [43], [44], [45].

Simple random sampling (SRS) was used to obtain the data across the three Local Government areas (LGA) in Ogun State, Nigeria. The selected LGAs are Ado-Odo/Ota, Ifo and Yewa South, which are in close proximity to each other. The choice of the target population reflects the views of both the urban and rural respondents, reflecting the demographics in the State. The focus is on the gender, age, school type and educational level of the distribution of the externalizing behavior patterns of the respondents.

The differences between the rural and urban externalizing behavior pattern is open for further research. The questionnaire was given to pupils and students of public/private primary and secondary schools. The sampling was solely on without replacement and the non-response was excluded from the final data. Non responses are categorized as incomplete data as a result of partial or no responses from the respondents. Inclusion of such data can be detrimental to the estimation of the population parameters.

The internal consistencies and the reliability of scale for the questions Q1–Q100 in the questionnaire is shown in Table 10. The table showed a high random nature of the data and is very reliable for statistical analysis.
