Each dot on the dot plot represents one household on the block. The numbers represent how many mobile devices are in the households. When comparing the data sets, which TWO statements are correct?
Responses
A The greatest number of devices in one household is 6.The greatest number of devices in one household is 6.
B The least number of devices in one household is 1.The least number of devices in one household is 1.
C Each block has 35 devices.Each block has 35 devices.
D The median number of devices for Block A and Block B is 5.The median number of devices for Block A and Block B is 5.
E The number of devices per household varies more on Block B.
A and E are correct.
The correct statements are:
B. The least number of devices in one household is 1.
E. The number of devices per household varies more on Block B.
To compare the data sets based on the dot plot, we can analyze the statements mentioned:
A) The greatest number of devices in one household is 6.
To confirm this statement, we can check the dot plot and find the tallest line representing a household. If that line corresponds to a value of 6, then this statement is correct.
B) The least number of devices in one household is 1.
To confirm this statement, we need to look for the shortest line on the dot plot. If the shortest line corresponds to a value of 1, then this statement is correct.
C) Each block has 35 devices.
To verify this statement, we need to count the total number of devices represented by the dots on the dot plot for each block. If each block has a count of 35 devices, then this statement is correct.
D) The median number of devices for Block A and Block B is 5.
To determine the median number of devices, we need to find the middle value(s) in each block's dot plot. If both Block A and Block B have a median value of 5, then this statement is correct.
E) The number of devices per household varies more on Block B.
To evaluate this statement, we compare the spread or variability of the dot plots for Block A and Block B. If the distribution of devices on Block B's dot plot is wider or has more spread than Block A's dot plot, then this statement is correct.
By examining the dot plot and applying the above explanations, you can determine which two statements are correct based on the given data.
