$\bigstar{\huge{\underline{\mathfrak{\red{Answer}}}}}$

1) Difference in Originality - Primary data are original because these are collected by the investigator from the source of their origin. Against this, secondary data are already in existence and therefore,are not original

2) Difference in Objective - Primary data always related to a specific object of the investigator. These data therefore do not need any adjustment for the concerned study. On the other hand, secondary data have already been collected for some other purpose. Therefore, these data need to be adjusted to suit the objective of study in hand.

3) Difference in Cost of Collection -Primary data are costlier in terms of time, money and efforts involved than the secondary data. This is because primary data are collected for the first time from their source of origin. Secondary data are simply collected from the published or unpublished reports. Accordingly, these are much less expensive.
