Advantages of Qualitative Data Analysis using longitudinal data
Because these studies require the use and collection of data in expand periods, they can determine patterns directly. Data analysis plan for qualitative research assist by utilizing them, it would be possible for researchers to know more about causation and effectiveness relationships and make connections in a more precise manner.
Missing Data
Missing data is the most challenging issue as there is no universally accepted correction, and inappropriate ones can lead to negative consequences.Coding in qualitative research analysis assistance helps to overcome the missing data by filling incomplete data.
Impact of Missing Data
Missing data can decrease the study’s statistical power and increase bias. Statistical power improves whenever the study’s sample size increases or variability of the study’s outcome measure should be accurate. Unfortunately, missing data negatively impacts the sample size and variability.
Irregularly Timed Data
Qualitative Data Analysis Help for dissertation helps in longitudinal studies generally encourage regularly occurring visits for Data collection. But study participation frequency, and total study visits vary due to scheduling limitations and dropout.

How to do a successful LQP?
But there’s more to it than money. Mixing up the research activities and keeping the panelists engaged is an important part of the successful LQP. Panelists need to participate in some research activity each period (monthly or biweekly), and the research company needs to provide clear, precise instructions on the various research activities. Research activities can run the gamut with an LQP: in addition to focus groups and in-depth interviews, panelists may participate in written, photo, or video diaries, observational research (cooking or shopping ethnographies, for example), kids’ parties or peer groups, and more.
What is the benefit of panelists?
A perhaps less obvious benefit is the remarkable rapport established between the researchers and panelists, and between the panelists themselves. This level of trust, especially amongst the panelists, cannot be developed in a typical two-hour focus group. Additionally, panelists can quickly move through the phases of team development – storming, norming, and performing – and become highly creative and productive research subjects.
Why is it important to have fun around the panel?
It is also important to create a sense of fun and belonging around the panel – asking respondents to arrive early, having plenty of snacks on hand for them to eat if they arrive straight from work, giving them a chance to socialize and bond, and conducting fun activities in the groups . The more comfortable they become with each other, the more they will let their guard down and open up in the research.
What are the benefits of a longitudinal panel?
One of the more obvious benefits is the ability to mix research activities and methodologies. Although the panel is longitudinal, it is qualitative, and nothing says you have to do the same thing each period. You can conduct groups, dyads, triads, in-homes, peer parties, kids’ parties, and observational research (watch them cook, shop, do the bills, bank online, change diapers, plan a vacation, etc.), and you can assign homework in the form of diary keeping (written, photo, and video) or consumer tasks. There is no limit to the number and types of activities you can plan (within reason and according to the objectives, of course).

Dear Letitia, the idea of combining these methods is not uncommon in recent past. However, the structure of your qualitative instrument should be amenable to quantitative methods. More importantly, the time span of the observations would have a lot of impact on the determination of the qualitative process, structure and ultimately, relevance.
All Answers (15)
I do not see why not in principle but the issue for me is one of resources. The quantitative element will need quite a few people to follow up to have sufficient power to detect effects and you will need to organize systems to collect the data over a period of time - another considerable cost.
