Quality Control

Malana Research Consult Unique Approach

Sampling & Coverage

We understand that quantitative data is only as good as the sample on which it’s based. That’s why Malana Research Consult (MRC) implements the highest quality sampling methods, giving every individual in a chosen population equal chance of being selected for our survey. Our teams conduct face-to-face interviews with respondents, and can cover the remotest locations, enabling us to provide a representative snapshot of opinion from some of the Africa’s most difficult to reach audiences.

Centralized Training

All teams are  trained on the back ground of the study, Quality control measures, Roles and responsibilities of interviewers, supervisors and  Quality Controllers (QCs), Interviewing skills, research protocols to be followed while in field as well as ethical conduct in research based on the ESOMAR CODE of conduct . The training is guided by a training manual and facilitated by Malana Research Consult team in conjunction with the client

We always emphasize a centralized training for the whole project team so as for the field team to have a uniform understanding of the study objectives and methodology. We strongly desist from having decentralized training by the supervisors. .

During the Research Assistants training, trainees are always subjected to tests to fully understand the competence of the team to execute the job. Trainees’ performance in the tests and during the practical activity shall be the criteria for final selection of enumerators for data collection and  Supervisor are selected based on experience and competence exhibited during the Research Assistants’ training and will be subjected to independent training to understand their roles while in the field.

Integrated Quality Control

Using android tablets with the most up to date software in the field, we receive data in real time at our main office in Kampala Uganda

By analysing GPS locations, interview lengths and recordings of interviews, our team closely monitors interview quality in even the remotest of locations, providing feedback to fieldworkers and minimizing interview errors.

Silent audio recordings

Malana research consult collects recordings of portions of the interview so that the validity of the data can be verified – the interviewer is not aware of which questions are recorded.

GPS coordinates

Collection of GPS coordinates for analytical and quality control purposes
In each of the locations, teams of 2-5 interviewers (depending on the sample size) conduct the interviews. Each team has a team supervisor who is charged with the responsibility of ensuring that fieldwork is conducted as agreed in each project guideline.

Unique identification codes

All surveys, supervisors, and interviewers are given unique identity codes. No duplication or replacement of this code is permitted.

Accompaniments: The Quality control (QC) team usually do 25% accompaniments, 10% back checks/visits and 15% call-back checks of the total interviews conducted by each interviewer. The purpose of this is to ensure that the interviewers follow all the instructions and procedures and conduct the interviews according to the quality standards specified.

While accompanying, the Field Supervisors and Quality Control person will take notes of all problems/challenges observed which will then be discussed on

Physical Back-checks: Before leaving the sampling area/Primary Sampling Unit (PSU/Enumeration Area), the Field Supervisor and Quality Control team usually select independently at least two or three of the five (or so depending) interviews conducted to ascertain the quality of data collected. The Field Supervisor and Quality Control team should first make sure that the sampling interval along the walk route has correctly been followed. They should then locate the person who was interviewed and ensure they were of the correct respondent’s selection methodology. Of all interviews to be conducted by each interviewer, 30% will be back-checked. The Field Supervisors and Quality Control team will make direct and personal contact with the respondents (face-to-face) to ascertain whether the interviews are done in respect to the protocol. Supervisors and quality control team should re-ask respondents a few relevant questions to validate the data and answers given by the respondent during interaction with the interviewers/data collector. All interviews that are back checked, spot checked and accompanied, as quality measures are captured on the contact sheet and shared together with the day’s updates from the field.

Call backs: During data collections our quality control team usually do between25% to 30% call backs from the sample of approached respondents to confirm whether interviewers/data collectors indeed talked to them within the selected sampling area as per the study.

Spot checks: The Quality Controller field team usually make an unannounced spot-checks on the field team, in this way, the field team is always kept in check.
