You are getting this error because QuickStats needs to create a table on your wordpress database but does not have needed privileges. Grant your wordpress mysql user CREATE privilege, or create the table manually by running the query below:
CREATE TABLE wp_jqstats (
id int(100) NOT NULL auto_increment,
url varchar(150) NOT NULL default '',
ip varchar(40) NOT NULL default '',
host varchar(250) NOT NULL default '',
date varchar(15) NOT NULL default '',
browser varchar(200) NOT NULL default '',
time varchar(20) NOT NULL default '',
referer varchar(255) NOT NULL default '',
domain varchar(255) default NULL,
PRIMARY KEY (id)
);
