Hi Patrizia,

I've got some questions for you to help clarify what the nature of the data is that you're dealing with and what you're trying to accomplish.  

First, what exactly is your research question(s)?  This/ these should guide your analysis plan.

Next, you said you are measuring "sentiment."  How are you determining the extent to which each record positive or negative?  What type/form of "score" are you giving them, and what is the lower and upper bounds of the possible range of scores (e.g., 0-9, unbounded).

Next, when you say you have "way more" tweets than newspaper articles, what is the exact quantity you have of each a) in total, and b) for each of your 14 days?

Answers to these questions might help us give some direction on an analysis plan and subsequent SPSS direction. 

Kind regards,

Brandi

Hi everyone!
I am writing on my master thesis and I have got a few questions. I will
compare the data of twitter and online newspapers within 14 days. My
variable is "sentiment" (how positive/negative is an article or tweet). Now,
I have way more tweets than articles. I am wondering now, how to compare it
best. Shall I take the mean value of each day and work out a regression? Is
there a more specific way?

Also, I want to measure, if twitter and online newspapers influence each
other. Now for this, I thought I will use the Rozelle Campbell baseline
formula, but now my question is: how can I execute that in SPSS? Is that
even possible? If not, can I do it in Excel?

Thank you so much for any help, and happy Easter!
