DESCRIPTION:In this webinar\, Paul Clarke (ISER) will discuss the consequ
 ences of Understanding Society’s decision to give participants the optio
 n of completing the survey questionnaire online via their web browsers. 
 He will give some background about why the move to web is taking place\,
  and discuss why survey mode can make such a difference to the results w
 e find.\n\nFollowing this\, Paul will formally define what is meant by a
  mode effect and why these can be difficult to estimate – and why experi
 ments are needed – and briefly review evidence from other studies (inclu
 ding the Understanding Society Innovation Panel) about the size of these
  effects\; this review will also discuss and critique the existing appro
 aches to estimating mode effects\n\nHe will then describe the experiment
  set up by the Understanding Society team\, give an overview of the ‘ins
 trumental variable’ methods we use to estimate these effects\, and how t
 hey addressed the challenge of understanding the impact of web mode when
  there are a wide range of analyses and statistical models they could us
 e.\n\nTo illustrate what the Understanding Society team did\, Paul will 
 take the user through two examples in which he estimates the mode effect
 s\, interpret what these effects mean for data quality\, and show the di
 fference that using web instead of face-to-face made to these analyses. 
 The webinar will finish by describing a simple way – using a random subs
 ample of participants who were interviewed face-to-face - for users to c
 heck whether they need to worry about the effect of web mode\, and what 
 to do if they find one.\n\nBook a place at https://register.gotowebinar.
