RELIABILITY AND ADEQUACY OF EAHM-PRICE DATA

had been discarded at random the remaining reports would have 
represented the State fully as well as the total number, and the 
resulting average would not have differed materially from the 
present average. 
The results of the June 15, 1925, questionnaire as to the price re- 
ceived by producers of corn in the nine crop-reporting districts of 
Iowa are shown in Table 6. In 59 of the 83 replies the prices given 
were on even 5-cent intervals, that is, were round numbers such as 
95, 100, 105, or 110 cents. The lowest prices were reported from 
those districts from which the most corn is usually sold, as for 
example, from districts 1, 2, and 5. The highest prices prevailed in 
districts 3 and 8, where corn is ordinarily shipped in at some time 
during the season. Sixty-four of the 83 replies were between 95 and 
105 cents both inclusive. The straight average price for the State 
was 103.3 cents as compared with the weighted average, 103.1 cents. 
The closeness of the straight average to the weighted average indi- 
cates that the reported prices as received tended to weight them- 
selves; that is, a larger number of price reports were received from 
the more important corn districts.
