    The mean of grouped data is preferred because it is more accurate as compared to the mean of ungrouped data. This is a wrong statement. In fact some accuracy is lost while grouping the data. However, it is easy to handle the grouped data as compared to ungrouped data. The statement should be that while we grouped the data, we do not loose much accuracy of the data interpreted in terms of the mean or the median, hence we can use the grouped data.

    The mean of ungrouped data may lead to wrong manipulation of the median therefore it is considered inefficient in most cases. This is also a wrong statement. What is original is ungrouped data not grouped data.
