Data Metrics - How to Standardise Raw Data - Using SmartPLS3
Posted: Sun Feb 22, 2015 3:42 pm
Hello Everyone,
I'd like to apologise if my question is inappropriate. I am just starting out with the use of smart PLS3 for my statistical analysis and still am figuring out bits and pieces .
I am currently trying to evaluate the influence of 7 Independent variables on one 1 dependent variable. Each of these variables have 3 measurement items and all are measured on a 7 point Likert Scale. I've been reading the J.Hair Book on SEM-PLS. He states that all data needs to be (z) standardised before running the software. his example states that there is an option to select Data Metric ( Mean 0, Var1) which would help convert the data to the required standardised format. I've been trying to use the SMARTPLS3 software, however The option to chose data metric isn't available. My query is as follows
1) Is the interface different in PLS2 as compared to 3 for running the calculations? as the screenshot provided in the book varies from the interface of this software.
2) Does the software automatically convert the 7 point likert scores to standardised values?
3) If it does not automatically standardise the raw data, how can i do it on the PLS3 software?
Would really appreciate any help in this regard and really sorry if my question is repetitive or silly. I am an absolute novice.
Many Thanks
