Session Length Check — sess_length

This function takes a dataframe as input as well as the minimum number of webpages in your web experiment or study, that a participant should have seen in order to be considered a complete (or plausible) participation. It flags the most extreme 10% of complete participations in the data as very slow or very fast.

Usage

sess_length_check(dataframe, min_pages = 6)

Arguments

dataframe: A dataframe containing WEXTOR data (needs to contain variables page_trail for the trail of webpages in the study and session_length for the overall time each participant spent on the study)
min_pages: Numeric. The minimum number of pages a participant must have visited in the study for their participation to be considered plausible. Defaults to 6.

Value

A dataframe with added variables sess_length_clean for only completed session lengths, otherwise NA and check_sess_length for a flag of the most extreme 10% of time needed to finish participation

Examples


data <- read_WEXTOR(path_to_file("BiFiX_data_raw.csv"))
new_data <- sess_length_check(data)
