    From the image above, which statement is most correct? - ProProfs

    From the image above, which statement is most correct?

    • The mean and mode are the same

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The mean value is higher than the median
    Explanation
    The mean value is higher than the median because the mean is calculated by adding up all the values and dividing by the total number of values, while the median is the middle value when the data is arranged in ascending or descending order. If the data is skewed towards higher values, the mean will be higher than the median.

    From the image above, which statement is most correct?

    • The mean and mode are the same

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The mean and median are approximately the same
    Explanation
    The mean is the average of all the values in a dataset, while the median is the middle value when the data is arranged in ascending or descending order. If the mean and median are approximately the same, it suggests that the dataset is symmetrically distributed without any extreme outliers.

    From the image above, which statement is most correct?

    • The mean and mode are the same

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The mean value is higher than the median
    Explanation
    The mean is calculated by summing all the values in a dataset and dividing by the number of values, while the median is the middle value when the data is arranged in ascending or descending order. If the mean value is higher than the median, it suggests that there are some larger values in the dataset that are pulling the mean upwards, indicating a right-skewed distribution.

    From the image above, which statement is most correct? - ProProfs

    From the image above, which statement is most correct?

    • The mean and mode are the same

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The mean value is higher than the median
    Explanation
    The mean is calculated by summing up all the values in a dataset and then dividing by the total number of values. The median is the middle value in a dataset when it is arranged in ascending or descending order. If the mean is higher than the median, it suggests that there are some larger values in the dataset that are pulling the mean up. This indicates that the distribution of the data is skewed towards the higher values. Therefore, the statement "The mean value is higher than the median" is most correct.

    From the image above, which statement is most correct? - ProProfs

    From the image above, which statement is most correct?

    • The mean and mode are the same

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The mean value is higher than the median
    Explanation
    The mean value is higher than the median when the data set has outliers or extreme values that pull the mean away from the center. In this case, the mean is influenced by these extreme values, causing it to be higher than the median. The median, on the other hand, is less affected by outliers and represents the middle value of the data set. Therefore, the statement "The mean value is higher than the median" is most correct based on the given information.

  • 8. 
    From the image above, which statement is most correct? - ProProfs

    From the image above, which statement is most correct?

    • The mean and mode are different

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The mean and median are approximately the same
    Explanation
    The mean is the average value of a set of numbers, while the median is the middle value when the numbers are arranged in ascending or descending order. If the mean and median are approximately the same, it suggests that the data is symmetrically distributed. This means that there are an equal number of values above and below the middle value, resulting in a similar average and middle value.

    From the image above, which statement is most correct? - ProProfs

    From the image above, which statement is most correct?

    • The mean and mode are the same

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The median value is higher than the mean
    Explanation
    The median value is higher than the mean when the data is skewed to the left, meaning that there are a few extremely low values that pull the mean down. In this case, the majority of the values are higher than the mean, causing the median to be higher.

    Rate this question:

  • 10. 
    From the image above, which statement is most correct? - ProProfs

    From the image above, which statement is most correct?

    • The mean and mode are the same

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The median value is higher than the mean
    Explanation
    The median value is higher than the mean when there are a few extremely high values in the data set. This is because the median is not affected by outliers, while the mean is influenced by them. Therefore, if the median is higher than the mean, it suggests that there are some unusually high values pulling the median up.

  • 11. 
    From the image above, which statement is most correct? - ProProfs

    From the image above, which statement is most correct?

    • The mean and mode are the same

    • The median value is higher than the mean

    • The mean value is higher than the median

    • The mean and median are approximately the same

    Correct Answer
    A. The mean value is higher than the median
    Explanation
    The mean value is higher than the median because the mean is calculated by summing all the values and dividing by the total number of values, while the median is the middle value in a sorted list of values. If the distribution is skewed towards higher values, the mean will be pulled up, resulting in a higher mean than the median.

    I collected data about average temperature in spring from 30 participants. I added the values together and they totalled 540 For this set of data, what is the value of : - ProProfs

    I collected data about average temperature in spring from 30 participants. I added the values together and they totalled 540 For this set of data, what is the value of :

    Correct Answer
    18
    Explanation
    The value of 18 represents the average temperature in spring collected from the participants. The total sum of the temperatures collected from the 30 participants is 540, which means that the average temperature can be calculated by dividing the total sum by the number of participants (30). Therefore, the average temperature in spring is 18.

    I collected data about number of radios in a house from 40 participants. I added the values together and they totalled 360 For this set of data, what is the value of : - ProProfs

    I collected data about number of radios in a house from 40 participants. I added the values together and they totalled 360 For this set of data, what is the value of :

    Correct Answer
    9
    Explanation
    The value of 9 represents the number of radios in a house. The data collected from 40 participants was added together and the total was 360. This means that the sum of all the individual values for the number of radios in each house is 360. Therefore, the value of 9 represents one of the individual data points, indicating that there were 9 radios in one of the houses.
