The scatter graph shows some information about eight cars. For each car it shows the engine size, in litres, and the distance, in kilometers, the car travels on one litre of petrol. What type of correlation does this scatter graph show?
The scatter graph shows some information about eight cars. For each car it shows the engine size, in litres, and the distance, in kilometers, the car travels on one litre of petrol. Another car of the same type has an engine size of 2.5 litres. Estimate the distance travelled on one litre of petrol by this car.
The scatter graph shows some information about eight cars. For each car it shows the engine size, in litres, and the distance, in kilometers, the car travels on one litre of petrol. Another car of the same type has a 1 litre engine. Estimate the distance travelled on one litre of petrol by this car.
In a survey, the outside temperature and the number of units of electricity used for heating were recorded for ten homes. What type of correlation does this scatter graph show?
In a survey, the outside temperature and the number of units of electricity used for heating were recorded for ten homes. Kyle wants to use a line of best fit to predict the number of units of electricity used for heating when the outside temperature is 30 degrees Celsius. This is outside the range of observed values, therefore Kyle's prediction may not be a reliable. This process is known as ___________.
The scatter graph shows the number of driving lessons and the number of tests needed to pass by ten people. What type of correlation does this scatter graph show?
The scatter graph shows the number of driving lessons and the number of tests needed to pass by ten people. What proportion passed on their first test?
The scatter graph shows the number of driving lessons and the number of tests needed to pass by ten people. Use a line of best fit to estimate the number of tests needed to pass by a person who has 50 lessons? (Round your answer to the nearest whole number, as you must take a whole test at a time!)
The scatter graph shows information about ten apartments in a large cosmopolitan city. The graph shows the distance from the city centre and the monthly rent of each apartment. What type of correlation does this scatter graph show?
The scatter graph shows information about ten newly-built one-bedroom apartments, in a large cosmopolitan city. The graph shows the distance from the city centre and the monthly rent of each apartment. Estimate the monthly rent for another newly-built one-bedroom apartment which is 2.8 km from the city centre.
The scatter diagram shows the number of ice creams sold in a shop each day against the temperature at midday that day. What type of correlation does this scatter graph show?
The scatter diagram shows the number of ice creams sold in a shop each day against the temperature at midday that day. What are the coordinates of the outlier?
The scatter diagram shows the height and weight of twenty babies aged 12 months. What type of correlation does this scatter graph show?
The scatter diagram shows the height and weight of twenty babies aged 12 months. The height and weight of one of the babies is not typical for babies aged 12 months. Where is this data on the scatter diagram?
The scatter diagram shows the height and weight of twenty babies aged 12 months. Oliver is 12 months old. His height is 75 cm. Using the line of best fit, estimate Oliver's weight.
The scatter diagram shows the height and weight of twenty babies aged 12 months. Ella is 12 months old. Her weight is 9 kg. Using the line of best fit, estimate Ella's height.
