The box plot above displays the 100m times for two groups. Since the "boys" group is mentioned as the correct answer, it can be inferred that the boys have the fastest runner based on their respective box plot. However, without the visual representation of the box plot, it is not possible to provide a detailed explanation.

The box plot above displays the 100m times for two groups. Since the question asks which group has the slowest runner, we can look at the box plot to compare the two groups. The "boys" group is represented by the box plot, and based on the position of the box plot and the outliers, it can be inferred that the "boys" group has the slowest runner.

The inter-quartile range (IQR) is a measure of the spread or dispersion of a dataset. It represents the range between the first quartile (Q1) and the third quartile (Q3). In the given box and whisker plots, the box represents the IQR. Comparing the boxes of Melbourne and Sydney, it is evident that the box for Sydney is larger, indicating a greater IQR. Therefore, Sydney had the highest inter-quartile range.

The box plot above shows the 100m times for two groups, with the girls' group having the most consistent times. This can be determined by looking at the width and length of the box plot for each group. The girls' box plot appears to be narrower and shorter, indicating that the range of times for the girls is smaller and there is less variation in their performances compared to the other group.

The spread refers to the range of values in a dataset. In this case, if the spread of girls' times is smaller compared to the spread of boys' times, it indicates that the girls' times are more consistent. A smaller spread suggests that the girls' times are closer together and less variable, while a larger spread for boys' times implies more variability and inconsistency in their performances. Therefore, the feature of spread helps prove that girls' times are more consistent than boys' times.

The Q3, also known as the third quartile, represents the upper boundary of the data distribution. In this case, if Brisbane has a higher Q3 value compared to Sydney, it means that the top 25% of temperatures in Brisbane are higher than the top 25% of temperatures in Sydney. Therefore, Q3 is a feature that helps prove Brisbane has higher temperatures than Sydney.

Based on the given information, the Parallel Box & Whisker Plots compare the test results of two different batteries, with 100 batteries tested for each type. Since the question asks for the battery with the worst result out of the 200 batteries tested, the answer is Battery B, as indicated by the second "B" in the answer choice.

The correct answer is Sydney. This can be determined by comparing the medians of the two box plots. The median is the middle value of a dataset when it is arranged in ascending order. In this case, the median rainfall in Sydney is higher than the median rainfall in Melbourne, indicating that Sydney had the highest median rainfall over the 50-day period.

The Parallel Box & Whisker Plots show the rainfall of two cities over a period of 50 days. By examining the plots, we can see that the boxes for Brisbane are narrower and more compact compared to Melbourne. This indicates that Brisbane had less variability in its rainfall measurements, making it the city with the most consistent rainfall.

Based on the given Parallel Box & Whisker Plots, we can see that the median line in the box plot for Brisbane is higher than the median line for Melbourne. This indicates that Brisbane had a higher median rainfall compared to Melbourne over the 50-day period. Therefore, the correct answer is Brisbane.

The correct answer is Melbourne. This can be determined by comparing the medians of the two box plots. The median is the middle value of a dataset when it is arranged in ascending order. In the given box plots, the median line of Melbourne is lower than that of Brisbane, indicating that Melbourne had a lower median rainfall.

The bar chart does not provide any evidence or data that supports the claim that boys' times are more consistent than girls' times. The spread and center of the data are not clearly shown in the chart, so it is not possible to determine if one gender has more consistent times than the other. Therefore, the correct answer is "Neither".

The bar chart displays the grades for different classes. The class with the lowest maximum grade can be determined by comparing the heights of the bars. In this case, Class A has the lowest maximum grade because its bar is the shortest among all the classes.

Based on the information provided, the question asks which battery lasted the longest out of the 200 batteries tested. The answer states that Battery B lasted the longest.

The correct answer is Sydney. This can be determined by comparing the lengths of the whiskers in the box and whisker plots for both cities. The whisker represents the range of the data, with the lower whisker indicating the minimum value and the upper whisker indicating the maximum value. In this case, the whisker for Sydney is shorter than the whisker for Melbourne, indicating that Sydney had a lower maximum rainfall compared to Melbourne over the 50-day period.

The bar chart does not provide any evidence or data that supports the claim that boys' times are more consistent than girls'. The chart only displays the spread and center of the data for both boys and girls, but it does not show any significant difference between them. Therefore, the correct answer is "Neither" as there is no feature in the chart that helps prove the consistency of boys' times compared to girls'.

The bar chart does not provide any evidence or data that supports the claim that girls' times are more consistent than boys' times. The chart only shows the spread of the times for both girls and boys, but it does not indicate any significant difference or pattern between the two genders. Therefore, the correct answer is "Neither" as there is no feature in the chart that proves the consistency of girls' times over boys' times.

The bar chart shows that the center of the boys' times is located at a lower value compared to the center of the girls' times. This indicates that, on average, the boys' times are faster than the girls' times. Therefore, the feature of the center helps prove that boys' times are faster than girls' times.

The Spread IQR (Interquartile Range) is a measure of the dispersion or spread of data. In this context, it refers to the difference between the upper quartile and the lower quartile of temperature data for both Sydney and Brisbane. If the Spread IQR is smaller for Sydney compared to Brisbane, it indicates that Sydney's temperatures are more consistent or less variable. Therefore, the Spread IQR feature helps prove that Sydney has more consistent temperatures than Brisbane.

The bar chart shows the minimum grades for each class. Class A has the highest minimum grade compared to Class B and Class C. Therefore, the correct answer is A.

The minimum, median, maximum, and bottom 25% values of the temperatures for Melbourne are all lower than those of Brisbane. This indicates that Melbourne generally has lower temperatures compared to Brisbane over the 30-day period.

The range in a box and whisker plot represents the difference between the maximum and minimum values. Looking at the plot, it is clear that Melbourne has a larger range compared to Sydney. Therefore, Melbourne had the highest range of rainfall over the 50-day period.

The box and whisker plots show the minimum rainfall for both cities over 50 days. Since the minimum rainfall for both cities is the same, it can be concluded that neither city had the highest minimum rainfall.

The interquartile range and median are the features of the parallel box plot that confirm the statement that Brisbane has a higher rainfall than Melbourne. The interquartile range represents the spread of the data and shows the range of rainfall values between the 25th and 75th percentiles. If the interquartile range of Brisbane is higher than that of Melbourne, it indicates that Brisbane has a wider range of rainfall values, suggesting higher rainfall. Similarly, the median represents the middle value of the data. If the median of Brisbane is higher than that of Melbourne, it indicates that Brisbane has a higher average rainfall over the 50-day period.

The maximum value and the top 25% of the data are the features that confirm the statement that Class A is the best performing class. The maximum value represents the highest test mark achieved in each class, so if Class A has the highest maximum value, it suggests that they have achieved the highest individual test mark. Similarly, the top 25% represents the upper quartile of the data, indicating the highest range of scores within each class. If Class A has the highest top 25% value, it suggests that they have a larger proportion of students with higher test marks compared to the other classes.
